| 摘 要： | 利用熔融接枝法制备了双峰聚乙烯接枝马来酸酐(bPE-g-MAH),将其用作聚碳酸酯/双峰聚乙烯(PC/bPE)共混物的增容剂。通过力学性能测试和扫描电镜分析,研究了bPE-g-MAH对共混物相容性和力学性能的影响。结果表明:bPE-g-MAH的加入使得PC和bPE两相的界面黏合作用增强,使PC/bPE共混物的冲击强度显著提高。

| Abstract: | Maleic anhydride grafted bimodal polyethylene(bPE-g-MAH) was prepared by melt grafting technology as a compatibilizer of polycarbonate(PC)/bimodal polyethylene(bPE) blends.The addition of the compatibilizer improves the impact strength and compatibility of the blends.The effects of bPE-g-MAH on compatibility and mechanical property of the blends were investigated by means of mechanical property test and SEM analysis.The results show that:with the addition of bPE-g-MAH,the interfacial adhesion between PC and bPE is improved,the impact strength of the blend increases obviously. |
