Issued: December 24, 2012
Filed: November 17, 2010

Inventors: Allen; Scott D. (Ithaca, NY)
Assignee: Novomer Inc. (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
