摘要
用浊点测定、傅里叶变换红外光谱、微差扫描热分析和透射电子显微镜等方法研究了苯乙烯-顺丁烯二酸酐交替共聚物(α-PSMA)与聚甲基丙烯酸甲酯(PMMA)的相容性。结果表明:α-PSMA共聚物与PMMA共混物在共混比7/93～30/70范围内相容性得到改善,其原因是由于α-PSMA与PMMA之间存在特殊的相互作用。
The miscibility of styrene/maleic anhydride alternating copolymer and poly (methyl methacrylate)blends was investigated by measuring the cloudy point and using FTIR.DSC and electronic microscope. The results show that the reason why the miscibility of blends of styrene/ maleic anhydride alternating copolymer and PMMA is improved over a limited mixing ratio is that there is specific interaction between styrene/maleic anhydride alternating copolymer and PMMA.
