SYNTHESIS OF AB AND ABA TYPES POLYSTYRENE (A)-POLYOXYETHYLENE(B) BLOCK COPOLYMERS AND CHARACTERIZATION OF THEIR STRUCTURES*
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, IR, UV. DSC, polarized microscopy and X-ray diffractionmethod and compared with mixture of homopolymers.
