Claim 7:
8. The activated solid catalyst component of claim 1, wherein the internal electron donor is represented by one of the following formulas:, where R1-R4, are the same or different and each R1-R4 is selected from the group consisting of hydrogen, a substituted hydrocarboyl group having 1 to 20 carbon atoms, an a unsubstituted hydrocarboyl having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 20 carbons, an alkoxy group having 1 to 20 carbon atoms, a heteroatom and combinations thereof and at least one of R1-R4 is not hydrogen; and
E1 and E2 are the same or different and each E1 and E2 is selected from the group consisting of a substituted hydrocarboyl group having 1 to 20 carbon atoms, an a unsubstituted hydrocarboyl having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 20 carbons, an alkoxy group having 1 to 20 carbon atoms, a heteroatom and combinations thereof
wherein X1 and X2 are each O, S, an alkyl group, or NR5 and wherein R5 is a hydrocarbyl group having 1 to 20 carbon atoms or is hydrogen; or, wherein:
each of R1 through R6 are independently H, F, Cl, Br, I, alkyl, cycloalkyl, cycloalkylalkyl, aryl, aralkyl, heterocyclyl, heterocyclylalkyl, heteroaryl, or heteroarylalkyl; or, wherein each of R7 through R14 are independently H, F, Cl, Br, I, alkyl, cycloalkyl, cycloalkylalkyl, aryl, aralkyl, heterocyclyl, heterocyclylalkyl, heteroaryl, or heteroarylalkyl groups.
