Addition polymer : ウィキペディア英語版 | Addition polymer
An addition polymer is a polymer which is formed by an addition reaction, where many monomers bond together via rearrangement of bonds ''without'' the loss of any atom or molecule. This is in contrast to a condensation polymer which is formed by a condensation reaction where a molecule, usually water, ''is'' lost during the formation. == Formation == (詳細はfree radical polymerization, cationic polymerization, anionic polymerization and coordination polymerization. Most of the common addition polymers are formed from unsaturated monomers (usually having a double bond).〔(【引用サイトリンク】 title=Addition Polymers )〕 This includes polyethenes, polypropylene, PVC, Teflon, Buna rubbers, polyacrylates, polystyrene, and PCTFE. Addition polymers are also formed from monomers that have a closed ring. Through coordination polymerization, even saturated monomers can form addition polymers. When two or more types of monomer undergo addition polymerization, the polymer formed is known as an addition copolymer. Saran wrap, formed from polymerization of vinyl chloride and vinylidene chloride, is an addition copolymer.
