Abstract
Two series of segmented copolyesters were synthesized, in which the flexible blocks were poly(ethylene terephthalate) (PET) and the hard blocks were fully aromatic triads as mesogens. The copolymers maintained the ability to form a mesophase at temperatures above the melting points when they contained only 12% equivalent p-hydroxyl benzoate (PHB) moiety as in PHB/PET random copolymer. With increasing length of the PET segments in the copolymers, their compatibility with PET matrix in blending was improved better than normal liquid crystalline polymers (LCPs) for in-situ composites. Some mechanical properties of the polyblends were primarily measured for potential usage in this respect.
