摘要： This invention relates to supported activators comprising the product of the combination of an ion-exchange layered silicate, an organoaluminum compound, and a heterocyclic compound, which may be substituted or unsubstituted. This invention further relates to catalyst systems comprising catalyst compounds and such activators, as well as processes to polymerize unsaturated monomers using the supported activators.For the purposes of this patent specification and the claims thereto, the term “activator” is used interchangeably with the term “co-catalyst”, the term “catalyst” refers to a metal compound that when combined with an activator polymerizes olefins, and the term “catalyst system” refers to the combination of a catalyst and an activator with or without a support. The terms “support” or “carrier”, for purposes of this patent specification, are used interchangeably and are any ion-exchange layered silicates.
