摘要： Olefins are polymerised in the presence of a catalyst comprising in combination:
(1) a titanium trichloride composition obtained by reducing TiCℓ₄ with an organoaluminum compound or a reaction product of an organoaluminum compound with an electron donor;
(2) an organoaluminum compound; and
(3) an alkoxy group- or phenoxy group-containing organosilicon compound of the formula:
R¹ n Si(OR²) 4-n
in which R¹ is a hydrogen or halogen atom or a C₁-C₂₀ hydrocarbon radical; R² is a C₁-C₂₀ hydrocarbon radical; and n is 0, 1, 2 or 3.摘要翻译： 烯烃在催化剂存在下聚合，所述催化剂组合包括：（1）通过用有机铝化合物还原TiC 14或有机铝化合物与电子给体的反应产物获得的三氯化钛组合物; （2）有机铝化合物; 和（3）下式的烷氧基或苯氧基的有机硅化合物：其中R 1是氢或卤素原子或C 1 -C 20的具有下式的R 1 nSi（OR 2）4-n的有机硅化合物 烃基; R 2是C 1 -C 20烃基; 且n为0,1,2或3。
