... Phthalate esters such as dioctyl phthalate (DOP) and dibutyl phthalate (DBP) are often used as plasticizers for polyvinyl chloride. Phosphate esters such as tricresyl phosphate (TCP) are also used to improve plasticity as well as flame retardancy and oil resistance. Polyvinyl chloride decomposes when exposed to light or heat, generating hydrogen chloride, and epoxy compounds are also used as plasticizers that capture this hydrogen chloride. ... *Some of the terminology that mentions "tricresyl phosphate" is listed below.

… ポリ塩化ビニルの可塑剤としてよく用いられるのは,フタル酸ジオクチルdioctyl phthalate(DOP),フタル酸ジブチルdibutyl phthalate(DBP)などのフタル酸エステル類である。可塑性のほか,難燃性や耐油性を改良するため,リン酸トリクレシルtricresyl phosphate(TCP)などのリン酸エステルも用いられる。ポリ塩化ビニルは光や熱によって分解し,塩化水素を発生するが,この塩化水素をとらえる働きをもつ可塑剤として,エポキシ化合物も用いられる。… ※「tricresyl phosphate」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
