Abstract

The present invention discloses a method for preparing a supported catalyst composition using spray drying. The supported catalyst composition is used in olefin polymerization.

Description

technical field [0001] The present disclosure relates to spray-dried catalyst compositions, methods for their preparation, and their use in processes for polymerizing olefins. In particular, the present disclosure relates to spray-dried catalyst compositions comprising methylaluminoxane and metallocene-type catalysts and / or conventional-type transition metal catalysts. Background technique [0002] The main focus of the polyolefin industry in recent years has been on the development of new catalysts providing new and improved products. Transition metal catalysts, such as for example metallocene catalysts are currently widely used in the manufacture of polyolefin polymers, such as polyethylene polymers. Transition metal catalysts generally require activators or cocatalysts in order to achieve commercially acceptable activity levels. Exemplary activators include methylaluminoxane (MAO) and molecular activators, or co-catalysts, such as Lewis acid borane. [0003] Furthermor...
