摘要

α-Phenyl ethyl potassium was synthesized and used in the preparation of AB type polysty-rene (A)-polyoxyethylene (B) block copolymer. The effects of polymerization time and temperaturewere studied. ABA type block copolymers were prepared by combining AB type block copolymerscontaining one hydroxyl end group using toluene diisocyanate as coupling agent. Both copolymerswere purified

characterized by NMR

UV. DSC

polarized microscopy and X-ray diffractionmethod and compared with mixture of homopolymers.
