【摘要】 聚对苯二甲酰氯代对苯二酚酯为一种高熔点的热致性液晶材料,难以加工成型。本文通过低温溶液法,采用间苯二甲酰氯、2,6-萘二甲酰氯作第三单体,进行共聚改性。分别讨论了大分子主链中因具有弯折键的第三单体的引入,导致共聚体的熔点、热性能、液晶性和结晶性能等变化。更多还原

【Abstract】 Poly-chloro-hydroquinont; terephthalate is a thermotropic polyester, which has high melting point and therefore is difficult to process. In this paper, we respectively used isophthalate dichloride and 2,6-naphthalene dichlorides as third monomers to modify the polyester, and prepared two kind of copolyesters, which have kink chain in the main chain of polymers.Now, we mainly discuss the effect of the kink chain on the properties of copolymers.更多还原
