Abstract
This invention is directed to processes for making polymer in the presence of a hydrofluorocarbon, and for the recovery of polymer substantially free of dissolved hydrocarbons and hydrofluorocarbons. The processes provided enables polymerization processes to be practiced with minimal fouling in the reaction system, and with the recovery of the hydrofluorocarbon and monomers for reuse in the reactor. The process of the invention utilizes a reactor system, a recovery system and a flare system that minimize environmental emissions of hydrocarbons, hydrofluorocarbons and associated decomposition products.
