摘要 制备了UCC型S-2铬系催化剂,研究了不同烷基铝助催化剂下该催化剂对乙烯与1-己烯的共聚合行为,考察了不同助催化剂和不同共聚单体浓度对聚合反应动力学行为及共聚物微观结构的影响。结果表明:加入助催化剂会消除反应的诱导期;加入共聚单体会降低催化活性,降低共聚物的相对分子质量;与采用三异丁基铝相比,采用三乙基铝作为助催化剂更有利于共聚单体的加入而形成短支链。 制备了UCC型S-2铬系催化剂,研究了不同烷基铝助催化剂下该催化剂对乙烯与1-己烯的共聚合行为,考察了不同助催化剂和不同共聚单体浓度对聚合反应动力学行为及共聚物微观结构的影响。结果表明:加入助催化剂会消除反应的诱导期;加入共聚单体会降低催化活性,降低共聚物的相对分子质量;与采用三异丁基铝相比,采用三乙基铝作为助催化剂更有利于共聚单体的加入而形成短支链。
