摘要
用核磁共振方法（ＮＭＲ）及差示扫描量热法（ＤＳＣ）测定了苯乙烯丙烯腈（ＳＡＮ）无规共聚物与均聚物系列聚甲基丙烯酸甲酯（ＰＭＭＡ），聚甲基丙烯酸乙酯（ＰＥＭＡ），聚甲基丙烯酸正丁酯（ＰｎＢＭＡ），聚甲基丙烯酸异丁酯（ＰｉＢＭＡ）共混体系的有关参数，比较全面地研究了影响ＳＡＮ与聚甲基丙烯酸酯类（ＰＭＡｓ）相容性的因素，对它们相容性的本质进行了探讨，得出了一些重要结论．
The misibility of blends of poly (styerene co acrylonitrile) (SAN) with poly (methyl methacrylate) (PMMA), poly (ethyl methacrylate) (PEMA), poly (n butyl methacrylate) (PnBMA), poly (i butyl methacrylate) (PiBMA) has been studied by means of NMR and DSC techniques. The results indicate that there are strong intermolecular interactions between the phenyl groups in SAN and and carbonyl groups in PMAs, the sequence distribution of SAN and dimensional conformations of PMA play critical roles in the miscibility of blends.
