NOVEL COMBINATIONS OF SILANE ELECTRON DONORS FOR USE IN CATALYST COMPOSITIONS |
摘要 |
Disclosed is a process for preparing an olefinic polymer comprising contacting at least one olefinic C3+ monomer and a catalyst composition comprising a Ziegler-Natta catalyst, dicyclopentyl dimethoxysilane as a first electron donor, and a second electron donor selected from the group consisting of methyl trimethoxysilane, methyl triethoxysilane, dimethyl dimethoxysilane, and mixtures thereof, under reaction conditions suitable to form an olefinic polymer. The polymer prepared using this method may exhibit significantly broadened molecular weight distribution than that achieved using any of the silane compounds alone, and may also exhibit desirable melt flow characteristics and xylene solubles levels. |
