The invention relates to catalyst compositions including at least one catalyst compound and at least one continuity additive such as poly-oxo-metal carboxylate compound and their use in the polymerization of olefins.

Continuity additives and their use in polymerization processes

The present invention relates to catalyst systems for polyolefin production, and more particularly, to catalyst systems for polyolefins used in producing films.

Ziegler-type catalysts having increased productivity

The present invention relates to a catalyst composition and a method for making the catalyst composition of a polymerization catalyst and a carboxylate metal salt. The invention is also directed to the use of the catalyst composition in the polymerization of olefin(s). In particular, the polymerization catalyst system is supported on a carrier. More particularly, the polymerization catalyst comprises a bulky ligand metallocene-type catalyst system.

Catalyst composition and methods for its preparation and use in a polymerization process

The present invention relates to a catalyst composition and a method for making the catalyst composition which comprises a polymerization catalyst and at least one gelling agent. The invention is also directed to the use of the catalyst composition in the polymerization of olefin(s). In particular, the polymerization catalyst system is supported on a carrier.

A process of producing a bimodal polyolefin composition is described, which includes in one embodiment contacting monomers with a supported bimetallic catalyst composition for a time sufficient to form a bimodal polyolefin composition that includes a high molecular weight polyolefin component and a low molecular weight polyolefin component; wherein the supported bimetallic catalyst includes a first catalyst component that is preferably non-metallocene, and a second catalyst component that includes a metallocene catalyst compound having at least one fluoride or fluorine containing leaving group, wherein the bimetallic catalyst is supported by an enhanced silica, dehydrated at a temperature of 800&#xb0; C. or more in one embodiment.

Bimodal polyolefin production process and films therefrom

The present invention relates to a composition of a carboxylate metal salt in combination with a heated polymerization catalyst to improve the flowability and operability of the catalyst. The invention also relates to methods for preparing the catalyst composition and to its use in a polymerization process.

Method for preparing a supported catalyst system and its use in a polymerization process

The present invention relates to a supported catalyst composition and a method for making the supported catalyst composition and its use in a process for polymerizing olefin(s). In particular, the invention is directed to a method for making a supported catalyst composition by combining a heated bulky ligand metallocene-type catalyst system with a carrier or an optionally heated carrier.
