Olefin Polymerisation Catalyst Containing a Cycloakane Dicarboxylate as Electron Donor |
摘要 |
A catalyst system useful in polymerizing olefins comprising a solid, hydrocarbon-insoluble catalyst component containing magnesium, titanium and halogen and an internal or external electron donor comprising a substituted hydrocarbyl four to eight-membered cycloalkane dicarboxylate wherein the substituents are positioned on the cycloalkane to place the dicarboxylate groups into adjacent conformational positions and wherein the substitutes contain 1 to 20 carbon atoms and may be joined to the cycloalkane structure to form a bicyclo structure.
