摘要
应用广角Ｘ射线衍射（ＷＡＸＤ）对２，２－双（４羟基苯基）丙烷，１，１０癸二醇与２－甲基－１，４－苯撑双（４氯甲酰）苯甲酸酯的一系列共聚酯进行了研究。发现组成不同时，共聚酯可形成３种不同的晶型，以此解释了其熔点变化的规律。对结晶度和晶粒尺寸变化的研究表明，晶粒尺寸与熔点的变化规律相一致。
In this paper, WAXD was used to investigate a series of liquid crystalline and non liquid crystalline sequential copolyester, which was synthesized from 1,10 decanediol, 2,2 bis(4 hydroxyphenyl) propane and the mesogenic monomer 2 methyl 1,4 phenylene bis(4 chloroformyl) benzoate. According to the 2,2 bis(4 hydroxyphenyl) propane and 1,10 decanediol, copolyesters form three types of crystal. The relationship between degree of crystallinity and their crystal structure of the copolyesters was studied. The melting temperature of the copolyesters is mainly depended on the crystal size.
