| titleOfInvention |
Process for polymerization in solution of olefins comprising thermally inactivating polymerization catalyst |
| abstract |
The present invention relates to a polymerization process, said process comprising: a) feeding a feedstock containing ethylene and at least one alpha-olefin having at least 3 to 12 carbon atoms into a polymerization reactor in a hydrocarbon solvent; b) contacting the raw material of step a) with a catalyst in the reactor to form a reaction mixture containing an ethylene-alpha-olefin copolymer; c) recovering the reaction mixture from the polymerization reactor as a reactor outlet stream comprising the ethylene-alpha-olefin copolymer, unreacted monomers and comonomers, a catalyst, and a hydrocarbon solvent; d) heating the reactor outlet stream to a temperature at least 5° C. above the temperature of the reaction mixture at the outlet of the reactor for a period of time between 1 and 250 seconds to deactivate the polymerization catalyst; e) separating hydrocarbon solvents, monomers and comonomers from the reactor outlet stream and recycling them to the polymerization reactor without further purification steps. |
