摘要
本文在前报的基础上,对带有不同取代基的第三单体对大分子链结构和性能的影响,采用2,5-二氯代对苯二甲酰氯和四氯代对苯二甲酰氯为第三单体进行共聚改性,讨论了取代基的性质和数量对共聚体的熔点、热性质、液晶性能和结晶性的影响。
We used 2, 5-dichloroterephthalate dichlorides and tetrachloroterephthalate dichlorides as third monomers to modify the polychloro-hydroquinone terephthalate and prepared two kind of copolyester, which are of thermotropic properties. In this paper, we mainly discuss the effect of numbers of substituted group on the chain structure and properties of cppolymer.
