Polymer polyfethylene butadiene

These include the vinyl addition polymers derived from common monomers like methyl methacrylate [9], acrylonitrile [10-12], styrene [13],butadiene [14], 4-vinylpyridine [15],acrylamide [15],andtetrafluoro ethylene [16]. In addition, selective polymers like polyfvinyl alcohol) [17],poly(N-vinyl pyrrolidone) [18], polyfethylene glycol) (PEG) [19], and others [20] have also been used. 

Polystyrene is the name of a homopolymer made from the single monomer styrene. When the name of a monomer comprises two or more words, the name should be enclosed in parentheses, as in polyfmethyl methacrylate) or poly(4-bromostyrene) to identify the monomer more clearly. This method can result in several names for a given polymer thus, polyfethylene glycol) , poly(ethylene oxide) , and poly(oxirane) describe the same polymer. Sometimes, the name of a hypothetical monomer is used, as in polyfvinyl alcohol) . Even though a name like polyethylene covers a multitude of materials, the system does provide understandable names when a single monomer is involved in the synthesis of a single polymer. When one monomer can yield more than one polymer, e.g. 1,3-butadiene or acrolein, some sort of stiuctural notation must be used to identify the product, and one is not far from a formal structure-based name.
