Abstract

New graft and block copolymers were synthesized by two procedures, each consisting of a sequence of cationic and free-radical polymerization reactions. One polymer component was a liquid crystalline side-group polymer, with the other polymer component being incorporated in crystalline grafts or in amorphous blocks. The copolymers were microphase-separated and underwent thermal transitions (glass, melting, isotropization) of each individual component.
