Abstract

Abstract: The crystallization of polycaprolactone(PCL),polyethylene glycol (PEG)andtheir block copolymers have been studied using DSC techniqtie. The results showed that thecomposition as well as the molecular weight of PCL and PEG affected the crystallinity of theblock copolymers. The crystallinity of the copolymer showed a maximLim value on standing.Some of the kinetic parameters on isothermo-crystallization have beeii calculated.

Key words: polycaprolactone, polyethylene glycol, block copolymer, crystallization
