Abstract
Catalyst systems and methods of forming the catalyst systems are described herein. The methods generally include contacting a support material with an activator to form a support composition, contacting a component with at least a portion of an aluminum containing compound including TIBAl, wherein the component is selected from the support composition, the transition metal catalyst compound and combinations thereof and contacting the support composition with a transition metal catalyst compound to form a supported catalyst system.
Claims13
A method of forming a catalyst system comprising:
- providing a support material;
- contacting the support material with an activator to form a support composition;
- providing a single site transition metal catalyst compound;
- providing a aluminum containing compound, wherein the aluminum containing compound comprises triisobutyl aluminum;
- and
- contacting the support composition with the transition metal catalyst compound to form a supported catalyst system, wherein the support composition is contacted with a first portion of the aluminum containing compound and the transition metal catalyst compound is contacted with a second portion of the aluminum containing compound prior to contact of the support composition with the transition metal catalyst compound.
