Though what is a polymer? A substance made of many repeating chemical units or molecules. A simpler way to think of polymers is as a paper clip chain. The paper clips are all made out of the same things, as they are linked together it illustrates the concept of polymers chemical unit repeating themselves. Depending on the substances used depends on the polymer created. Most polymers contain carbon and hydrogen, though they can also have oxygen, chorine, fluorine, nitrogen, silicon, phosphorous and sulfur. PVC contains chlorine, Nylon contains nitrogen, Teflon contains fluorine, and as well Polyester and polycarbonates contain oxygen.
