PVC/SBR-g-(BA-co-St)共混物性能的研究
关键字：PVC/SBR-g-(BA-co-St)共混物
本实验主要是利用种子乳液聚合的方法在SBR(丁苯橡胶,St/Bd=30/70，200nm)胶乳上接枝BA(丙烯酸丁酯)和S（t 苯乙烯）共聚物，制得SBR-g-(BA-co-St)三元接枝共聚物，用于增韧PVC。考察了SBR-g（BA-co-St）中壳层接枝BA，MMA 的不同比例的对其共混物冲击性能，拉伸性能以及透光的影响。

P(HB-co-HHx)结晶过程的原位红外及二维相关分析研究
关键字：：P(HB-co-HHx),2D IR,结晶
PHB 是PHAs 中最简单的一种，但因结晶度很高而硬且脆。人们往往通过加入不同的结构单元，如HHx，来调控PHB 的结晶行为，从而改善PHB 的性质。本工作以温度梯度为外扰，以P(HB-co-HHx)的C=O 伸缩振动区为对象, 研究了P(HB-co-HHx)从140oC 逐步降温到30oC 的结晶行为。
