8 8 PVP and more... LUVITEC, LUVICRSS and CLLACRAL VAL 2. LUVITEC 2.1 Vinylpyrrolidone homopolymers LUVITEC K-grades PVP is a white, hygroscopic powder with a weak characteristic odor. In contrast to most polymers, it is readily soluble in water and a large number of organic solvents, such as alcohols, amines, acids, chlorinated hydrocarbons, amides and lactams. n the other hand, the polymer is insoluble in the common esters, ethers, hydrocarbons and ketones. PVP is markedly hygroscopic. This property combined with outstanding film formation, initial tack and adhesion to different materials, high capacity for complex formation, good stabilizing and solubilizing capacity, insensitivity to ph changes, ready radiation-induced crosslinkability as well as good biological compatibility have made PVP one of the most frequently used specialty polymers. PVP is synthesized by free-radical polymerization of N-vinylpyrrolidone in water or alcohols with a suitable initiator. By selecting suitable polymerization conditions, a wide range of molecular weights can be obtained, extending from low values of a few thousand daltons to approximately 2.2 million daltons. LUVITEC K-grades Versatile polymers for technical applications Soluble in many systems Hygroscopic Film formation Adhesion Initial tack Complex formation Dispersing Stabilization Solubilization Crosslinkability Stable in a wide ph range Biological compatibility Toxicologically safe Binding

9 9 PVP and more... LUVITEC, LUVICRSS and CLLACRAL VAL Product range BASF offers a wide range of vinylpyrrolidone homopolymers with different molecular weights (K-values) under the name LUVITEC K. The products are available as a powder or as aqueous solutions. Characteristic parameters of all LUVITEC K-grades are listed in Table 1. Details of the test methods and product specifications are available on request. High molecular weight PVP powders LUVITEC K 80, K 85, K 90 and K 90 HM are packed under an inert gas atmosphere to maintain its molecular weight. This packaging guarantees a storage stability of the powder product in the original container at room temperature for at least 3 years.

10 10 PVP and more... LUVITEC, LUVICRSS and CLLACRAL VAL Typical product properties Ash The ash content is determined by heating the sample to 800 C for 6 h. All LUVITEC K-grades show an ash content of 0.02%. Details of the method can be obtained on request (Table 3). Viscosity The rise in viscosity with increasing concentration depends essentially on the K-value. While in the case of the low molecular weight K 17 and K 30 grades, a 5 10% increase in concentration has only a slight effect on the viscosity, changes by a factor of 5 or more can be found for the high molecular weight products (Fig.1). Molecular weight The average molecular weight (Mw) of the LUVITEC K-grades extends from a few thousand daltons to about 2.2 million daltons. The number-average molecular weight (Mn) rises in parallel with this from around 2,000 daltons to around 400,000 daltons. The weight average and the number average were determined by GPC analyses; calibration was done with narrowly distributed PVP samples which had previously been characterized by light scattering (Table 3). Glass transition temperature With the exception of LUVITEC K 17 powder, the glass transition temperatures of LUVITEC K homopolymers lie within a similar, relatively high temperature of C (Table 3). Particle size distribution The particle size spectrum of the LUVITEC K powder grades varies considerably since different drying processes are used to produce the powder (Table 3). Color The color is determined using aqueous solutions according to the method of the European Pharmacopoeia. A guide value lighter than BY5/B5/R6 applies to all LUVITEC K- grades. Details of the method can be obtained on request (Table 3). viscosity in mpa s at 23 C LUVITEC K 115 LUVITEC K 90 LUVITEC K 90 LUVITEC K 80 K-value 116 K-value 97 K-value 90 K-value 80 water absorption in % LUVITEC K 60 LUVITEC K 30 LUVITEC K 17 K-value 55 K-value 30 K-value Solids content in % rel. humidity in % Figure 1: Dependence of the viscosity on the solids content of aqueous LUVITEC K-solutions; Brookfield RVT Viscometer, spindle 3, 100 rpm at room temperature Figure 2: Moisture absorption of LUVITEC K-grades (film thickness: 2 mm) at 23 C after saturation

11 11 PVP and more... LUVITEC, LUVICRSS and CLLACRAL VAL Compatibility and Film Forming Properties The outstanding compatibility of Polyvinylpyrrolidone with a huge number of compounds like organic and inorganic salts, dyes, active compounds, plasticizers, bacteria, blood opens up a wide field of opportunity and applications for LUVITEC in different industries. Polyvinylpyrrolidone films are clear, transparent, hard and brittle. These properties can be selectively modified, for example, tack and brittleness, by using plasticizers like: water, glycerin, glycol, polyglycols, fatty acid derivates, phthalates, Hexamoll, sorbitol, cellulose derivates. Solubility of PVP ne of the outstanding properties of PVP is its universal solubility both in hydrophobic and in extremely hydrophilic solvents (Table 2). To produce solutions of PVP from powder, it is advisable to add the powder to the solvent in portions while stirring; in this way, formation of lumps of powder can be avoided. When using higher molecular weight PVPs and also when producing more concentrated solutions, the rate of dissolution can be significantly increased by raising the temperature to 50 C 60 C. Soluble in Insoluble in Hygroscopicity The marked hygroscopicity of PVP is sufficiently well known. Moisture absorption is almost independent of the molecular weight. The moisture content curve (Figure 2), determined using a 2 mm PVP film, is characteristic of all LUVITEC K-grades.

12 12 PVP and more... LUVITEC, LUVICRSS and CLLACRAL VAL Crosslinkability High molecular weight LUVITEC K-grades (for example LUVITEC K 90) can be crosslinked at elevated temperature (70 90 C) by adding small quantities of a peroxide (for example tert.-butyl peroxipivalate, H22/CuCl2) or persulfate in aqueous solution and under nitrogen. By contrast, aqueous LUVITEC K 30 solutions can best be crosslinked by raising the ph to 11 at elevated temperature (approximately 90 C) under nitrogen. PVP films can be crosslinked even at room temperature by radiation curing (electron beam, gamma or X-rays) using megarads. Crosslinking is also known with UV light in the presence of a UV initiator (for example 4,4'-diazidostilbene-2,2'- di-sodium sulfonate) at nm and a light intensity of mw/cm 2. When crosslinked, PVP becomes insoluble in all solvents. In contrast to soluble PVP, crosslinked PVP is capable of swelling only in polar solvents (for example water or ethanol). The extent of swelling depends on the crosslinking density. n account of its outstanding adhesion and physiological compatibility, weakly crosslinked PVP with a high water content (hydrogel) is employed as a skin-adhesive gel.

Vinylpyrrolidone copolymers LUVITEC and CLLACRAL VAL An attractive extension of the PVP product range with specifically modified properties By incorporating selected comonomers into the VP polymer chain, specific properties of the VP homopolymers (LUVITEC K-grades) can be modified. This opens up a variety of possibilities for new applications. Such comonomers include vinylacetate (VA) and N-vinylcaprolactam (VCAP).

15 15 PVP and more... LUVITEC, LUVICRSS and CLLACRAL VAL Product description LUVITEC VA 64 The moisture absorption of PVP can be reduced specifically by the partial incorporation of less hydrophilic comonomers, such as vinylacetate (Figure 4). LUVITEC VA 64, which contains 40 wt. % of vinylacetate, has proved its worth in numerous technical applications. LUVITEC VA 64 is nonionic. It's comonomer ratio is optimized to make it soluble in both water and organic solvents such as ethanol, isopropanol, n-propanol, glycerin, methylene chloride, esters and ketones. LUVITEC VA 64 powder is not soluble in ether or aliphatic hydrocarbons without auxiliary solvents. Water absorption of LUVITEC VA 64 and K water absorption in % 60 LUVITEC K LUVITEC VA As compared with PVP homopolymers, the glass transition temperature of LUVITEC VA 64 of 105 C is significantly lower, giving it a markedly improved melting behavior.

16 16 PVP and more... LUVITEC, LUVICRSS and CLLACRAL VAL LUVITEC VPC 55 K 65 W As in the case of LUVITEC VA 64, moisture absorption compared to the VP homopolymer can be reduced by the partial replacement of VP by the less hydrophilic vinylcaprolactam. LUVITEC VPC 55 K 65 W is a good film former. The aqueous solution shows a reversible cloud point at 65 C. CLLACRAL VAL CLLACRAL is a special hydrophobic, modified vinylpyrrolidone/ vinylacetate copolymer with a glass transition temperature of approx. 106 C. Due to the special modification, CLLACRAL VAL can be used as a thickener in a wide ph-range between 3 8, with optimal performance at a ph of approx. 5. In addition CLLACRAL VAL can be used as protective colloid in the production of resin dispersions and mixing preparation of resin solutions with polymer dispersions.

Product range and description LUVICRSS a crosslinked and thus, insoluble vinylpyrrolidone homopolymer, belongs to the class of products called PVPP (polyvinylpolypyrrolidone).

19 19 PVP and more... LUVITEC, LUVICRSS and CLLACRAL VAL 3.2 Typical product properties LUVICRSS A series of compounds are adsorbed in acid aqueous media or solvent mixtures by the formation of hydrogen bonds or as a result of dipolar interactions. These include for example phenolic substances, synthetic or natural anionic dyes of the most varied categories, such as anionically modified azo dyes, azomethine dyes and triphenylmethane dyes (Figure 5). Furthermore, mycotoxins, such as the aflatoxins B1 and G1, zearalenone (Figure 6) or patulin are adsorbed to the polymer. The hydrogen bonding can be completely reversed by increasing ph. In addition, PVPP can form complexes with iodine or hydrogen peroxide in powder form or from solutions. Unlike non-crosslinked, chainlike PVP, PVPP is insoluble in both organic and inorganic solvents. For this reason, no molecular weight can be determined for PVPP. The chemical and physical crosslinking of the polymer renders LUVICRSS resistant to extreme ph-values and elevated temperatures. For guidance, 95% of the particles of the standard form of LUVICRSS are smaller than 300 μm The determination was carried out by means of laser diffraction on the powder.
