1 Playing With Polymers Name Site #1: Polymer Basics Go to Mrs. Hellinga s Chemistry page. Click on the polymer power point to answer the next 4 questions. 1. What is polymerization? It is the process of chemically bonding to form. 2. What are some examples of natural polymers? Cotton, silk, wool, and natural rubber are all polymers made from plant or animal products. Protein is an essential ingredient in living matter and is made up of monomers called. It is also called a chain. The found in our cells is also a polymer. The monomer units of DNA are and the polymer is known as a polynucleotide. 3. What are some examples of synthetic (manmade) polymers? Some synthetic polymers are manmade and fabrics such as polyester,, and rayon. is a synthetic polymer used to make a variety of products, such as water bottles, plastic, and kitchen utensils as well as safety, computers, and rocket engines. Polymers are also used in as substitutes for human, such as bones and arteries. 4. What substances are used to make synthetic polymers? They are made from materials called, which are made from. Petroleum is made from the remains of and that have beneath sediments at the bottom of the ocean. Over time, and changed the remains into petroleum, which is a resource. Site #2: Hands-On
