摘　　要：采用氯化原位接枝法制备氯化聚乙烯接枝甲基丙烯酸甲酯(CPE-g-MMA),并对其红外谱图进行了分析。研究了CPE-g-MMA与纳米CaCO_3协同增韧PVC。结果表明,CPE-g-MMA在1730 cm^(-1)处有明显的羰基吸收峰;与CPE相比,CPE-g-MMA具有良好的力学性能;CPE-g-MMA增韧效果显著;CPE-g-MMA与纳米CaCO_3对PVC有协同增韧作用。A kind of CPE-g-MMA copolymer was synthesized by in-situ chlorinating graft copolymerization, which was analyzed by the IR spectrum. The effects of the toughening of CPE-g-MMA composited by nano-CaCO3 on PVC were studied. The results show that an obvious absorption peak at 1 730 cm^-1 , owning to carbonyl group, can be found in CPE-g-MMA. CPE-g-MMA has good mechanical properties. The effect of toughening of CPE-g-MMA is remarkable. CPE-g-MMA and nano-CaCO3 have synergistic toughening on PVC.
