7-以Et（Ind）2 ZrCl 2甲基铝氧烷为催化剂体系，在不降低催化剂活性和分子量的情况下进行了辛烯基二甲基苯基硅烷与乙烯的共聚反应。聚合物样品中的共聚单体含量为0.15-1.0摩尔%的水平，并且将反应性苯基硅烷基团后处理成不同的烷氧基和卤代硅烷基团，例如SiF、SiCl、SiOCH 3和SiOCH 2CH 3。后处理反应对共聚物的摩尔质量或热性能（用差示扫描量热法测量）没有重大影响。反应途径几乎与共聚单体含量无关，并且反应达到70-100%转化率。© 2004 Wiley Periodicals，Inc.聚合物科学杂志A部分：聚合物化学42：1461-1467，2004年
7-Octenyldimethylphenylsilane was copolymerized with ethylene via Et(Ind)2ZrCl2 methylaluminoxane catalyst system without loss of catalyst activity or decrease in molar mass. The comonomer contents in the polymer samples were at a level of 0.15–1.0 mol % and the reactive phenylsilane groups were posttreated to different alcoxy- and halosilane groups, for example, SiF, SiCl, SiOCH3, and SiOCH2CH3. The posttreatment reactions had no major effect on the molar masses or on the thermal properties (measured with differential scanning calorimetry) of the copolymers. The reaction pathways were nearly independent of the comonomer contents and the reactions reached 70–100% conversions. © 2004 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 42: 1461–1467, 2004
