Abstract
Compositions useful in propylene polymerization catalysts, and in particular solid, hydrocarbon-insoluble, catalyst compositions containing magnesium, titanium, and halogen and further comprising a modifier compound with structure (1): wherein Q1 is an oxygen containing group selected from CH2—O—R1, C(═O)—R1 and C(═O)—O—R1 and Q2 is selected from R2 and O—R2; R1 to R5 each being independently selected from H, alkyl, aryl, allyl, alkaryl, arylalkyl groups, optionally comprising one or more heteroatoms.
