摘要: 利用Molau实验、红外光谱、电子扫描显微镜等研究了尼龙1010与马来酸酐接技改性聚丙烯(PP-g-MAH)共混体系的结构,结果表明,尼龙1010分子链中胺基或亚胺基与PP-g-MAH上的酸酐发生了化学反应,生成的接枝共聚物起到了共混体系增容剂的作用,改善了体系的亲合性。

Abstract: The morphology structure of nylon-1010/PP-g-MAH blend systems,as well as nylon-1010/PP blends were studied. The Molau experiments and the IR analysis of the xylene extraction fractions of the blends showed that the reactions between -NH2 or -NH-groups of nylon-1010 and maleic anhydride groups of PP-g-MAH took place during the melt blending, and the PP-g-NY1010 copolymer formed by the reactions acted as a compatibilizer. Also it could be found from the SEM photographs that the affinity between the nylon-1010 and PP-g-MAH was improved to some extent as compared with that of nylon-1010lPP blends.
