Abstract
This invention relates to a process to polymerize olefins comprising: i) contacting one or more olefins with a catalyst system comprising: 1) a support comprising an organoaluminum treated layered silicate and an inorganic oxide; and 2) a bisphenolate compound; and ii) obtaining olefin polymer having high molecular weight and layered silicate dispersed therein. Preferably the support is in the form of spheroidal particles.
