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).

Self-associating cellulose-graft-poly(ɛ-caprolactone) (cellulose-g-PCL) copolymers were successfully synthesized via homogeneous ring-opening polymerization (ROP) of ɛ-CL onto softwood dissolved pulp substrate in ionic liquid 1-N-butyl-3-methylimidazolium chloride ([Bmim]Cl). An organic catalyst N,N-dimethylamino-4-pyridine (DMAP) was compared with the traditional metal-based catalyst (Sn(Oct)(2)) as the
