Abstract
The present invention relates to the use of thermally triggered compounds that when used with a polymerization catalyst in a polymerization process results in the controllable generation of one or more catalyst inhibitors that renders the polymerization catalyst substantially or completely inactive.
Claims13
A catalyst composition comprising a polymerization catalyst and a thermally triggered compound that at a specified temperature chemically transforms into one or more catalyst inhibitors that deactivate the catalyst composition.
A catalyst composition comprising a bulky ligand metallocene catalyst compound, an activator, a support, a thermally triggered compound, wherein thermally triggered compound is unreactive to the catalyst composition at 25° C.
