| 摘 要： | 采用ＤＭＡ和ＴＥＭ系统研究了聚丁二烯－聚甲基丙烯酸甲酯的嵌段共聚物（ＰＢＤ－ｂ－ＰＭＭＡ）与聚氯乙烯（ＰＶＣ）共混体系的相容性问题。结果表明：ＰＶＣ／ＰＢＤ－ｂ－ＰＭＭＡ共混体系具有部分相溶性。相容的程度与共混体系的组成、组分聚合物的分子量以及共聚物中ＰＢＤ和ＰＭＭＡ嵌段的比例密切相关。

| Abstract: | The driscibility of PVC/PBD-b-PMMA blends has been studied. The results of DMA and TEM reveal that PBD-b-PMMA and PVC are partially ndscible. The mis cibility depends on the composition of the blends, the moleculax weight of the component polymers, and the proportion of PBD and PMMA in the block copolymers. The miscibility of PVC-5 with the copolymers is better than that of PVC-3 and PVC-7. When the proportion of PBD and PMMA are almost equal, the thescibility increases with the moleculax weight of PBD-b-PMMA. |
