Abstract:

采用溶胶-凝胶法,将苯乙烯-丙烯酸共聚物(PSA)包覆于955Davison硅胶上得到无机/有机复合微球载体,并在2,6-二［1-(2-异丙基苯基亚胺基)乙基］吡啶/Fe(acac)3均相催化剂中浸渍后得到负载型双亚胺基吡啶铁催化剂.该催化剂在生产高结晶度(72%)聚乙烯的同时,还能生产一定量的α-烯烃.考察了不同膜材料以及聚合条件(不同助催化剂,压力,温度,Al/Fe摩尔比)对聚合活性以及聚合产物性能的影响,发现温度对聚合产物的α-烯烃与聚乙烯的质量比影响最大,助催化剂类型既影响催化剂的活性,也对最终产物的性质有着很大的影响.氯化镁处理的PSA作为膜材料时,负载2,6-二［1-(2-异丙基苯基亚胺基)乙基］吡啶/Fe(acac)3所得到聚乙烯分子量较低(Mw=11.9×104),结晶度较大(72%),熔融指数MI较高(2.35g/10min),可作为双峰聚乙烯中的低分子量部分加以利用.
