摘　　要：采用不同熔融焓增韧改性剂CPE对PVC进行了改性,研究了CPE对PVC/CPE共混料的影响。结果表明:不同熔融焓的增韧改性剂CPE对PVC/CPE共混料的流变性能、缺口冲击强度、拉伸冲击强度和焊接强度都有较大的影响;含氯质量分数为36%左右、熔融焓(DSC法)≤1.4 J/g的CPE比较适合作为PVC材料的冲击改性剂。PVC was modified by toughening modifier CPE with different melting enthalpy,and the effect of CPE on PVC/CPE blend was studied.The results showed that the toughening modifier CPE with different melting enthalpies had a great influence on the rheological properties,notch impact strength,tensile impact strength and welding strength of PVC/CPE blends;CPE with chlorine content of about 36%and melting enthalpy(DSC method)≤1.4 J/g was more suitable as impact modifier for PVC materials.
