Abstract:
A catalyst for the homopolymerization or copolymerization of CH 2 ═CHR olefins, made from or containing the product obtained by contacting: (i) a solid catalyst component made from or containing Ti, Mg, Cl, and an internal electron donor compound, wherein the solid catalyst component contains from about 0.1 to about 50 wt % of Bi, based upon the total weight of the solid catalyst component; (ii) an alkyl aluminum compound and, (iii) an external electron donor compound having the formula:   (R1) a Si(OR2) b  wherein R 1  and R 2  are independently selected from the group consisting of alkyl radicals with 1-8 carbon atoms and a is 0 or 1 and a+b=4.

Claim (Index 4):
The catalyst according to  claim 1 , wherein the internal electron donor compound is selected from the group consisting of alkyl and aryl esters of optionally substituted aromatic polycarboxylic acids, esters of malonic acids and esters of glutaric acids.
