| Abstract: | By means of living anionic polymerization, a series of poly(styrene-ε-caprolactone) block copolymers were synthesized. The block copolymer is confirmed by GPC, column fractionation and infra-red spectra. The ring-opening polymerizations of ε-caprplactone by using living polystyrene, the properties of corresponding block copolymers and their structures were studied. The block copolymers exhibit microphase separation, and present multiphases which consist of amorphous polystyrene segments, amorphous poly-e-caprolactone segments and crystalline poly-e-eaprolactone segments. |
