US 2012/0232236 A1 · SUPPORTED NONMETALLOCENE CATALYST, PREPARATION AND USE THEREOF

Abstract

This invention relates to a supported nonmetallocene catalyst and preparation thereof. The supported nonmetallocene catalyst can be produced with a simple and feasible process and is characterized by an easily controllable polymerization activity. This invention further relates to use of the supported nonmetallocene catalyst in olefin homopolymerization/copolymerization, which is characterized by a lowered assumption of the co-catalyst as compared with the prior art.

A process for producing a supported nonmetallocene catalyst, comprising the steps of:

dissolving a magnesium compound and a nonmetallocene ligand in the presence of an alcohol in a solvent, to obtain a magnesium compound solution;
mixing a porous carrier or a thermally activated porous carrier with the magnesium compound solution to obtain a slurry;
drying the slurry, or introducing into the slurry a precipitating agent, to obtain a composite carrier;
and treating the composite carrier with a chemical treating agent selected from the group consisting of a Group IVB metal compound to obtain the supported nonmetallocene catalyst.
