【摘要】 在实验室通过在稀土催化剂配制时引入芳烃试剂的方法 ,考察了芳烃对稀土催化双烯烃聚合的影响。与作为聚合溶剂组分的芳烃导致催化活性降低的作用不同 ,在稀土催化剂配制时引入芳烃可提高催化活性 ,并在一定程度上可降低聚合产物相对分子质量。更多还原

【Abstract】 Effect of aromatic agent on isoprene polymerization with rare earth catalyst was investigated in the laboratory by the means of adding aromatic agent in the course of catalyst aging. In contrary to the function of aromatic agent as polymerization solvent or as a component of polymerization solvent that reduced the catalytic activity, aromatic agent as aging additive could enhance catalytic activity and lower the molecular weight of the polymer product.更多还原
