| 摘 要： | 采用一种含有强极性官能团的新型增韧剂马来酸酐接枝（乙烯／甲基丙烯酸酯）共聚物（E／MAK）-g-MAH]对聚碳酸酯（PC）进行增韧研究。实验结果表明，随着（E／MAK）-g-MAH含量的增加，PC／（E／MAK）-g-MAH共混体系的冲击强度显著提高。当（E／MAK）-g-MAH质量分数为20％时，冲击强度达59．6kJ／m^2，是纯PC冲击强度的近6倍。另外（E／MAK）-g-MAH还使共混体系的断裂伸长率提高，流动性得到明显改善。

| Abstract: | Polycarbonate(PC) was toughened by a new type of toughening agent maleic anhydride grafting ethylene/methacrylate copolymer(E/MAK)-g-MAH] which contained polar functional groups.The results showed that impact strength of PC/(E/MAK)-g-MAH blend increased markdedly with the inreasing of(E/MAK)-g-MAH content.When(E/MAK)-g-MAH content was 20%,the impact strength reached 59.6 kJ/m~(2),which was nearly six times as much as that of pure PC.In addition,the elongation at break was increased and the flowability was improved markedly. |
