General description
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).
Application
ε-caprolactone is popularly used in the preparation of poly caprolactone (PCL).
