英文摘要The composites of thermotropic liquid crystalline copolyesters ((p-hydroxy benzoic acid) -terephthalic acid-resorcin) (HB-TA-RES) and poly(butylene terephthalate) -poly( tetramethylene glycol) thermoplastic elastomer (PBT-PTMG) with different copolyester content or copolyester composition were prepared by in-situ polycondensation method. The obtained (HB-TA-RES)/PBT-PTMG were characterized by POM,TGA,WAXD,SEM and theological analysis. Liquid crystalline behavior of the composites was observed when the 1413 content in copolyester was 40 mol% and copolyester content in composite was 30 wt% similar to 70 wt% or copolyester content in composite was around 50 wt% and HB content in copolyester was 20 mol% 80 mol%. When the copolyester content in composites <= 50 wt % or HB content in copolyester <= 60 mol %, no obvious phase separation happened. The molecular structure of copolyester in composites was more homogeneous and the crystallization of HB was limited. The good thermal stability of ( HB-TA-RES)/PBT-PTMG composites with thermotropic liquid crystalline behavior was obtained as compared with the corresponding homocopolyester and the viscosity of the composites was lower than that of the matrix PBT-PTMG especially when the copolyester content was more than 30 wt%. Good processability of the composite is expected in the application.
