| 摘 要： | 采用扫描电镜，红外光谱（ＩＲ），Ｍｏｌａｕ实验等方法，研究了乙烯－丙烯酸无规共聚物对共聚酰胺和低密度聚乙烯共混体系的增容作用，研究结果表明：ＥＡＳ可以明显改善ＣＰＡ／ＬＤＰＥ共混体系的相容性其增容机理是氢键作用及在熔融共混过程中ＥＡＳ分子上的部分－－ＣＯＯＨ基与部分ＣＰＡ的端氨基发生酰胺化反应所生成的ＥＡＳ－ｇ－ＣＰＡ恰为共混组分的界面相容剂。

| Abstract: | The compatibilization of poly (ethylene-co-acrylic acid) Random copolymers onCPA/LDPE Blends were studied by the SEM, IR, Molau experiments. The results showthe graft copolymers EASang-CPA, which Resulted from the reaction between -COOHgroups of EAS and terminal-NH, groups 0f CPA during melt blending, act as inter facialcompatibilizer. Hydrogen bonds interactions also promote compatibility. |
