Abstract
A process for preparing a supported metallocene/aluminoxane solid catalyst comprises preparing a water-in-oil emulsion of water and an inert solvent by using an emulsifier, adding dropwise the emulsion to a solution of an organoaluminium compound in an inert solvent to carry out the reaction to obtain a suspension of the particulate aluminoxane, followed by adding a solution of a metallocene to the above suspension to support the metallocene on the aluminoxane. The solid catalyst thus obtained can be used in the polymerization and copolymerization of olefins. Polymerization can be carried out by slurry polymerization, bulk polymerization, gas phase polymerization, etc.
