    摘要: A solid, hydrocarbon-insoluble, catalyst component useful in polymerizing olefins containing magnesium, titanium, and halogen further contains an internal electron donor comprising ##STR1## wherein R is selected from C.sub.1 -C.sub.8 alkyl, C.sub.6 -C.sub.9 aryl or C.sub.1 -C.sub.8 alkoxy groups; and wherein X and Y are N-R', O, P(O)(OR'), P(O)R', or S, and R' is selected from hydrogen, C.sub.1 -C.sub.8 alkyl and alkoxy, and C.sub.6 -C.sub.9 aryl groups, provided that up to two Y groups may be CR'.sub.2 groups.
