摘要/Abstract

摘要： 苯乙烯-马来酸酐共聚物(SMa)与聚碳酸酯(PC)的相容性与SMa中Ma的含量有关,Ma摩尔含量在26-28%附近时相容性较好.通过FTIR、SEM等研究,发现SMa与PC在熔融共混中产生了接枝共聚反应。

Abstract: The compatibility of polycarbonate (PC) with styrene-maleic anhydride copolymer (SMa) varies according to the Ma content of SMa, good compatibility being achieved when the Ma content of SMa is about 26-28 mole%.
Results from DSC, FTIR, ¹³C-NMR and SEM studies indicate a graft copolymerization takes p]aoe between PC and SMa during the process of melt blending.

Key words: styrene-maleic anhydride copolymer, FTIR, colycarbonate, blends, SEM graft copo ymerization
