摘要：
A catalyst composition for the polymerization of olefins comprising the combination of one or more Ziegler-Natta procatalysts comprising one or more transition metal compounds; one or more aluminum containing cocatalysts; and a mixture comprising two or more selectivity control agents (SCA's), corresponding to the formula: (CH3O)nSi(OR)4-n, wherein R, independently each occurrence, is C2-12 alkyl, C3-12 cycloalkyl, C6-18 aryl or (poly)alkyl-substituted aryl, or C7-18 poly(aryl)-substituted alkyl, and n is an integer from zero to 4.
