2 12 ABSTRACT Polyurethane reactive hot melt adhesives (PUR) are isocyanate-capped prepolymers prepared from polyester and/or polyether glycols and a diisocyanate monomers or polyisocyanate. The different NCO content of PUR have been synthesized by polyhexanediol adipate (PHA), polypropylene glycols (PPG), and 4,4'-methylene diphenyl diisocyanate (pure-mdi) as the main ingredient. The PUR prepolymers are NCO-terminated, and they will be cured in the presence of moisture to generate highly crosslinked structure. The PUR with different isocyanate (NCO) content was studied on rheology, thermal and mechanical properties of PUR film. The effects of NCO/OH molar ratio on the morphology and physical properties of PUR were investigated by attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), differential scanning calorimetry (DSC) and universal testing machine. The results showed that the PUR had a high degree of micro phase separation and the hydrogen-bonded urea signal increases significantly under the higher NCO content. As the NCO content increase, the degree of hydrogen bonding of the hard segments and the glass transition temperature (T g ) increase. PUR prepolymer with higher crystalline content showed better green strength and the slower adhesion rate. Because the higher degree of crosslinking can prevent moisture diffusion into the PUR film, so leading to incomplete curing and hinder the crystalline behavior of the soft segment. It hence causes a lower initial adhesive strength.
