Organosilane compounds having the structural formula ##STR1## wherein R is a linear or branched C.sub.1-4 alkyl, 4-methyl-piperidyl, C.sub.6-12 aryl or C.sub.5-7 cycloalkyl; R.sup.1 is hydrogen, methyl or ethyl; R.sup.2 is methyl or ethyl and; n is 4 to 7. These organosilane compounds are useful as electron donors in Ziegler-Natta type catalyst systems.
具有结构式##STR1##的有机硅化合物,其中R是线性或支链的C.sub.1-4烷基,4-甲基哌啶基,C.sub.6-12芳基或C.sub.5-7环烷基;R.sup.1是氢,甲基或乙基;R.sup.2是甲基或乙基;n为4至7。这些有机硅化合物在齐格勒-纳塔类型催化剂系统中作为电子给体是有用的。
