摘要： This invention is directed to a polymerization process that is carried out at relatively high productivity levels and with relatively low fouling. The process includes mixing together a catalyst system, at least one monomer and a hydrofluorocarbon to produce the polymer. The reaction is carried out such that little to no chlorine containing hydrocarbons are present.

摘要： Embodiments of the present invention relate to measuring and controlling static in a gas phase reactor polymerization. In particular, embodiments relate to monitoring carryover static in an entrainment zone during gas phase polymerization to determine the onset of reactor discontinuity events such as chunking and sheeting. Embodiments also relate to monitoring carryover static to determine the need for effective additions of continuity additives that minimize reactor static activity and thereby preventing discontinuity events.

摘要： 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.
