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.

Olefin polymerisation catalyst containing a cycloakane dicarboxylate as electron donor

An olefin polymerization process comprises gas-phase polymerization of at least one olefin monomer in a reactor using a Ziegler-Natta or metallocene catalyst system in the presence of at least one suitable radical-generating compound in an amount sufficient for polymer modification and subsequent stabilization of such compound and generated radicals before post-reactor heat processing.

Olefin polymerization process in the presence of a radical generating system

A metallocene catalyst may be temporarily and reversibly passivated by contact with an effective amount of an unsaturated hydrocarbon passivating compound.

Latent metallocene catalyst systems for olefin polymerization

A gas-phase olefin polymerization process in a plug flow reactor uses a catalyst system containing a magnesium halide supported titanium-containing component, an organoaluminum component, and at least one external electron donor component; in the process a first external donor component is added to the reactor at an injection point axially near an injection point for the supported transition metal containing component, and at least a second external donor component is added to the reactor axially downstream from the injection point for the first external donor component.
