摘要

Process for deactivating a catalyst active species in a stream of polu00cdmero olefu00cdnico, process to reduce corrosu00e7o, clogging or incrustau00c7u00e7o produu00c7u00e7o equipment and recuperau00c7u00e7o of olefin and composiu00c7u00e7o polimu00c9rica.Process for deactivating an active catalytic species in a stream of polymer olefu00ednico coming out of a polymerization reactor and neutralize the waste catalyst, as well as to reduce corrosion.Clogging or fouling of equipment for production and recovery of olefins and provide antioxidant properties to a polymer olefu00ednico comprising adding a desativador catalyst and a metal salt of phosphoric acid or alkali earth silicate fosfu00f4nico a stream of polu00edmer The olefu00ednico out if a polymerization reactor.Each in an amount at least sufficient to deactivate catalytic active species in the polymer chain and neutralize the waste catalyst, respectively, and subsequ00faentemente recovering the resulting polymeric product.
