The crystallization of polycaprolactone (PCL),polyethylene glycol (PEG) and their block copolymers have been studied using DSC technique. The results showed that the composition as well as the molecular weight of PCL and PEG affected the crystallinity of the block copolymers. The crystallinity of the copolymer showed a maximum value on standing. Some of the kinetic parameters on isothermo-crystallization have been calculated.
