摘　　要：选用ＣＰＥ和ＣＰＥ／ＰＶＣ为改性剂．用双辊熔融共混的方式对ＴＰＵ的共混改性进行了系统的研究，对ＴＰＵ／ＣＰＥ和ＴＰＵ／ＣＰＥ／ＰＶＣ共混体系的性能进行了测试分析及对比。结果表明：选择适宜的ＴＰＵ种类和ＣＰＥ、ＣＰＥ／ＰＶＣ分别组成二元和三元共混体系，能明显改善ＴＰＵ的加工特性，并且基本保待了ＴＰＵ优良的耐油性和耐寒性。In this paper, thermoplastic polyurethane elastomer(TPU) blended with chlorinated polyethylene (CPE) and CPE/PVC were studied systematically by melt blending with two roll.The oil resistence, low temperature resistence and rheology properties of TPU/CPE and TPU/CPE/PVC blends were measured, analysed and compared.The results indicate that the processing characteristics can be significantly improved by blending the suitable type of TPU with CPE and CPE/PVC, and the good properties of oil and low temperature resistence can be retained.
