Methods of controlling molecular weight distribution of polymers and compositions thereof
Patent No. 8,324,337
Issued: December 24, 2012
Inventors: Allen; Scott D. (Ithaca, NY)
A catalyst, co-catalyst, and/or chain transfer agent is added at a time after initiation of an addition polymerization reaction to produce a polymer product with a widened molecular weight distribution relative to having all of the components in the original reaction mixture. The catalyst, co-catalyst, or chain transfer agent may be added discretely or continuously to the reaction to produce a product with a bimodal, trimodal, or other broadened molecular weight distribution
