| 摘 要： | 用热致性液晶高分子材料对塑料进行共混改性，借助液晶的在位复合制取自增强塑料是近年来许多人感兴趣的课题，我们合成了质量比为４０／６０的ＰＥＴ／ＰＨＢ共聚酯，用它对ＰＥＴ进行共混改性，用差示扫描量热（ＤＳＣ）、动态力学粘弹谱，以及小角激光光散射（ＳＡＬＳ）进行结构和性能的考察，表明ＰＥＴ／ＰＨＢ共聚酯对ＰＥＴ有增塑和促进结晶的作用。

| Abstract: | Thermotropic liquid crystalline PET/PHB copolyester by weight rate 40/60 was prepared. The blend modification of PET(40)/PHB(60) copolyester on the PET was studied by DSC, dynamic mechanical spectrum and small angle light scattering(SALS). It has been shown that there are at two states of PET/PHB in PET resin: in one state, PET/PHB is soluble in PET; in another, PET/PHB takes dispersion state, so that will effect both plasticization and nucleator and/or accelerator of crystallization. |
