ACTIVATOR-SUPPORTS IMPREGNATED WITH GROUP VIII TRANSITION METALS FOR POLYMER PROPERTY CONTROL
摘要
<p>Methods for controlling properties of an olefin polymer using a Group VIII transition metal-modified activator-support are disclosed. The melt index of the polymer can be decreased and the molecular weight of the polymer can be increased via the addition of the transition metal-modified activator-support to the polymerization reactor system.</p>
