| 摘 要： | 合成了１，４－环己烷二甲醇共聚改性的聚对苯二甲酸乙二酯，用示差扫描量热和傅立叶变换红外方法研究了该体系的等温结晶动力学和结晶度，结果表明，共聚物组成和结晶温度均会影响材料的结晶行为，这将有利于控制和改善ＰＥＴ的加工性。

| Abstract: | series of 1,4 cyclohexane dimethanol modified poly(ethylene terephthalate) copolymers were synthesized. The isothermal crystallization and crystallinity of these samples were investigated by means of DSC and FT IR. The results show that both the composition and the crystallization temperature tack effect on crystallization behaviors, which might be helpful for controlling and improving the material processing properties. |
