SYNTHESIS AND CHARACTERIZATION OF LIQUID CRYSTALLINE MULTI-BLOCK COPOLYMERS,POLY[1,6-BIS(4-OXYBENZOYL-OXY)HEXANE TEREPHTHALATE]-b-BISPHENOL A POLYCARBONATE

Received Date: 30 June 1998

A series of liquid crystalline multi-block copolymers poly [1,6-bis(4-oxybenzoyl-oxy)hexaneterephthalate]-b-bisphenol A polycarbonate (PHTH-6-b-PC) with different segment lengths were synthesizedin tetrachloroethane by solution polycondensation in which hydroxyl terminated PC and acyl chlorideterminated PHTH-6 were used. It is found that block copolymers with high molecular weight and well-defined structures were obtained. All the block copolymers exhibit a nematic liquid crystalline texture.
