|Section2= |Section7= }} Poly(vinyl acetate) (PVA, PVAc, poly(ethenyl ethanoate): commonly referred to as wood glue, white glue, carpenter's glue, school glue, Elmer's glue in the US, or PVA glue) is an aliphatic rubbery synthetic polymer with the formula (C4H6O2)n. It belongs to the polyvinyl esters family with the general formula -()-. It is a type of thermoplastic. == Properties == The degree of polymerization of poly(vinyl acetate) is typically 100 to 5000 while its ester groups are sensitive to base hydrolysis and will slowly convert PVAc into polyvinyl alcohol and acetic acid. Under alkaline conditions, boron compounds such as boric acid or borax cause the polymer to cross-link, forming tackifying precipitates or toys such as Slime and Flubber. A number of microorganisms can degrade polyvinyl acetate; most commonly, damage is caused by filamentous fungi however there are also algae, yeasts, lichens and bacteria that have been shown to degrade polyvinyl acetate. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「polyvinyl acetate」の詳細全文を読む スポンサード リンク
