Addition Polymers. Addition polymers such as polyethylene, polypropylene, poly(vinyl chloride), and polystyrene are linear or branched polymers with little or no cross-linking.As a result, they are thermoplastic materials, which flow easily when heated and can be molded into a variety of shapes.olyethylene has no taste or odor and is lightweight, nontoxic, and relatively inexpensive. It is used as a film for packaging food, clothing, and hardware. Most commercial trash bags, sandwich bags, and plastic wrapping are made from polyethylene films.
