The morphology, structure and properties of ternary blends VECTRA, PEEK,TOBC-PEEK were investigated using WAXD, SEM and mechanical test. With interfacial adhersion, the liquid crystalline polymer(LCP) could form microfiber in certain extent and disperse into the matrix of PEEK. The strength and modulus increased and reached the maximum in the blend containing 20% VECTRA. The crystallization behavior of the blend was obviously affected by the addition of block copolymer. SEM photographs showed that the high content of LCP possessed "core-shell" structure.
