Abstract: Block copolymers containing poly(aryl ether ketone) unit and different lengths of thermotropic liquid crystalline polyesters(TLCP) segments were synthesized by high temperature solution polymerization. The chemical structure, thermal properties and liquid crystalline behavior of the block copolymers were investigated by FTIR, DSC and PLM respectively. A single glass transition revealed that the two blocks had good a compatibility. The length of TLCP segment had a significant influence on the copolymer's liquid crystalline behavior. When the molecular weight of TLCP reduced to 2965, liquid crystallinity of copolymer disappeared. The block copolymers showed a typical nematic threaded texture which differed from polyester's.

Key words: Poly(aryl ether ketone), Block copolymer, Thermotropic liquid crystalline, Nematic texture
