摘　　要：以三氯氧钒-混合烷基铝为催化体系,以己烷为溶剂、氢气为相对分子质量调节剂研究了混合烷基铝对聚合物相对分子质量及其分布的影响,合成了门尼粘度、相对分子质量及其分布、乙烯含量、第三单体含量与国外同类产品4802基本相同的乙丙橡胶,应用性能研究结果表明,合成的样品性能与国外同类产品相当。In this paper,taking vanadium oxytrichloride-mixed alkyl aluminium as catalytic system,hexane as solvent,hydrogen as relative molecular weight regulator,the impact of the alkyl aluminum for the polymer relative molecular mass and relative molecular mass distribution was studied.Mooney viscosity,relative molecular mass and relative molecular mass distribution,ethylene content,the third monomer content of synthesized EPDM was same with target products.The results of application performance showed that the performance of the synthesized sample is equal of target product.
