Abstract:
The present invention relates to the use of at least one acid and at least one base and/or at least one reductant and at least one oxidant that when used with a polymerization catalyst in a polymerization process results in the controllable generation of a catalyst inhibitor that renders the polymerization catalyst substantially or completely inactive.
