Polyolefins
Polyethylene, polypropylene, ethylenevinyl acetate, ionomer, polybutylene, polymethylpentene, polydicyclopentadiene) Polyolefin homopolymers are made from ethylene, propylene, butylene, and methyl pentene. Other olefin monomers such as pentene and hexene are used to make copolymers. Because

different monomers. In a copolymer, the monomer chains can be random, alternating, or grafted. A terpolymer is the combination of three different monomers. Combining monomers in various combinations is key to producing the wide range of plastic resins, all with differing properties. Polymers
