PHASE STRUCTURE AND THERMAL BEHAVIOR OF LIQUID CRYSTALLINE MULTI-BLOCK COPOLYMERS,POLY1,6-BIS(4-OXYBENZOYL-OXY)HEXANE TEREPHTHALATE-b-BISPHENOL A POLYCARBONATE
Liquid crystalline multi-block copolymers poly [1,6-bis(4-oxybenzoyl-oxy)hexane terephthalate]-b-bisphenol A polycarbonate (PHTH-6-b-PC) with different segments of polycarbonate (PC) and thermotropicpolyester PHTH-6 were synthesized in tetrachloroethane at 144~146℃, The influence of segment length onthe resulting phase structure and thermal behavior of block copolymers was also discussed. It is demonstratedby TEM and DMA that the resulting block copolymers show a considerable microphase separation. Thedegree of phase separation and the thermal behavior of the block copolymers are strongly dependent on themolecular weight of the segments incorporated.
