| 摘 要： | 用动态力学分析（ＤＭＡ）和傅利叶变换红外光谱（ＦＴＩＲ）研究了氢化聚丁二烯－ｂ－聚甲基丙烯酸甲酯（ＨＰＢＤ－ｂ－ＰＭＭＡ）共聚物增容剂对聚氯乙烯（ＰＶＣ）与线性低密度聚乙烯（ＬＬＤＰＥ）共混体系的增容作用．增容剂使共混物中两相的玻璃化温度发生变化，说明其相容性增加．ＦＴＩＲ的结果表明，增容剂中羰基与ＰＶＣ的α氢形成氢键，使ＣＯ，Ｈ─Ｃ及Ｃ─Ｃｌ的振动频率变化，峰形加宽．

| Abstract: | The poly(butadiene-b-methyl methacrylate)(PBD-b-PMMA) copolymer has beenhydrogenated to form hydrogenated HPBD-b-PMMA copolymer which can be used as a com-patibilizer for PVC/LLDPE blends.The results of DMA and FTIR show that HPBD-b-PMMA is an excellent compatibilizer which changed the T_gs of two phases in blends.Thehydrogen bonds are considered to be formed between C=O groups of PMMA and H-C-Clgroups of PVC,which weak the interaction between different macromolecules. |
