Best Answer: millions of things. Polyethylene is the most popular plastic in the world.It has a very simple structure, the simplest of all commerical polymers. A molecule of polyethylene is a long chain of carbon atoms, with two hydrogen atoms attached to each carbon atom.t is used to provide coatings to paper and paperboard products for packaging of liquids such as milk and fruit juices, and to provide a moisture barrier to paper and woven cloth. It is also used for the coating of foil to provide a heat-seal layer in multilayer film structures.
Uses of poly(chloroethene) (polyvinyl chloride). Poly(chloroethene) is used in building and construction, for example in making window and door profiles and in making pipes (from guttering to sewers, and ducting for cables). Figure 1 Uses of poly(chloroethene).hloroethene (vinyl chloride) is also used to produce co-polymers, for example with ethenyl ethanoate (vinyl acetate). The co-polymer can be processed at much lower temperatures than poly(chloroethene) homopolymers of the same relative molecular mass.
