用途
用途
ウレタンの原料、高分子ポリエステル原料、樹脂改質剤。
用途
ε-カプロラクトンはその大部分がε-カプロラクタムの原料として消費される[3]。また、高度に特殊化したポリマーのモノマーとしても用いられる。開環重合させるとポリカプロラクトン(PCL)が生成する。
使用
ε-Caprolactone is widely used as a monomer in the manufacturing of highly specialized polymers. It is mainly utilized as a precursor to caprolactam. It finds an application in the synthesis of polyglecaprone, which is used as a suture material in surgery.
一般的な説明
ε-caprolactone is a cyclic ester. Ring opening polymerization of ε-caprolactone initiated by, tributylin n butoxide, ethyl magnesium bromide, or samarium acetate or heteropolyacid, leads to the formation of poly caprolactone (PCL).
