摘要
利用核磁共振氢谱和广角X射线衍射法研究了生物可降解共聚物聚对苯二甲酸-共-丁二酸丁二醇酯(PBST)的结构及结晶性能,并与聚丁二酸丁二醇酯(PBS)进行比较。结果表明:PBST为无规共聚物,其晶体结构为三斜晶系,PBS为均聚物,为单斜晶系,PBST的结晶度和结晶尺寸均比PBS的小。
The structure and crystallization behavior of poly（ butylene succinate-co-terephthalate） （PBST）, a biodegradable copolymer, were studied by nuclear magnetic resonance spectrometry and wide-angle X-ray diffraction and were compared with those of poly（ butylene succinate） （PBS）. The results showed that PBST was an atactic copolymer with a crystal structure of triclinic crystalline system when PBS was a homopolymer with a crystal structure of monoclinic system. PBST had lower crystallinity and crystal size than PBS.
