Abstract

Wholly aromatic polyester, LCP, was blended with PET to produce self-reinforced composites using an ultrasonically assisted single screw compounding extruder. Ultrasonic intensity was varied to induce in-situ compatibilization in the blends and was found to decrease pressure, and affect morphological, rheological and mechanical properties. PET and LCP homopolymerization, as well as their copolymerization through possible esterification/ transesterification reactions leading to an increase in their viscosities and mechanical properties was observed in the melt state under certain conditions.
