Abstract
A solid, hydrocarbon-insoluble, catalyst component useful in polymerizing olefins containing magnesium, titanium, and halogen further contains an internal electron donor comprising a compound containing electron donating substituents with a structure: wherein D1 and D2 are selected individually from and R, R2, R3, R4, R5, R6, and R7 individually are hydrocarbon or substituted hydrocarbon groups containing 1 to 20 carbon atoms and R2, R3, R4, R6, and R7 may be hydrogen; R4 may be —NR2; and wherein groups R1 and R2, R2 and R3, R3 and R4, R3 and R5, and groups R6 and R7 may be joined to form a cyclic structure.
