Abstract

Abstract The effects of liquid crystalline polymers’ structure, thermal history and compatibilizers on the transition temperatures of polysulfone with thermotropic liquid crystalline polymers’ in-situ composites were studied. The compatibility of polysulfone and liquid crystalline polymers obeyed the similar structure rule, and it could be improved by adding block copolymers.High heating rate could get a big peak in DSC curve, and it is easy to obtain T_g value by second heating. The thermal mechanical properties of these blends were also studied.
- liquid crystalline polymer,
- polysulfone,
- block copolymer,
