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: A process for polymerizing one or more monomers is provided. In at least one specific embodiment, the process includes preparing a mixture comprising the one or more monomers, a catalyst system and a flourinated hydrocarbon, preferably a hydrofluorocarbon. A fluorinated hydrocarbon containing stream, a polymer product stream and a waste stream are recovered from the mixture. At least a portion of the waste stream is sent to a non-flare decomposition system to produce a destructed waste stream, and the destructed waste stream is released to atmosphere.

摘要: This invention relates to a process to increase the amount of polymer solute in a polymerization medium or effluent comprising introducing a fluorocarbon into the polymerization medium or effluent in an amount effective to increase the amount of polymer solute in the polymerization medium or effluent by at least 3% without causing precipitation of polymer solute from the polymerization medium or effluent, as compared to the same polymerization medium or effluent without the fluorocarbon present. This invention also relates to a process to reduce the viscosity of a polymerization medium or effluent comprising introducing a fluorocarbon into the polymerization medium or effluent in an amount effective to reduce the viscosity of the polymerization medium or effluent by at least 3% without causing precipitation of polymer solute from the polymerization medium or effluent, as compared to the same polymerization medium or effluent without the fluorocarbon present.
