摘要： 本文研究了P(MMA-MAA)/PEO氢键复合物对一些聚合物共混体系的增容效应。首次用机械共混方法制备了P(MMA-MAA)/PEO氢键复合物。该复合物不能被甲醇革取,其热失重行为不是其组分聚合物的加和,表明此复合物不是简单的共混物。实验结果证实,该复合物可以改进PMMA/PEO体系的相容性,改善PVC共混体系的力学性能和加工性能。

Abstract: Aseries of poly (methyl methacrylate-methacrylic acid)/poly (ethylene oxide) intermacro-molecular complex has been successfully prepared through hydrogen bonding by mastication through a twin-roller. The experimental results show that the the complex can not be extracted by methanol and has a better thermal stability as compared with its constituent. The complex is an efficacious compati-bilizer for quite a few polymer blend systems. PMMA/PEO (67/33) after blending with a small amount of the complex [PMMA/PEO/P(MMA-MAA)/PEOcomplex), 63/30/7] is plasticized quite well, and its mechanical properties get improved. SEMand TEM observations reveal that the presence of P(MMA-MAA)/PEO complex will reduce the size of the domains and increase the homogeneity of the system.
