method for the treatment of polymer, which is prepared by polymerization of at least one alkene, in particular etheen or propene in a vapour phase - reactor and objects.produced by application of the treated polymer.

摘要

A melt finish process is disclosed herein for working up solid, particulate polymer from a vapor state polymerization reactor, which reactor employs high yield catalysts, whereby the polymer is moved out of the reactor and into a post polymerization zone characterized by essentially adiabatic polymerization and the heat of such polymerization is used in raising the temperature of and melting said solid, particulate polymer to form molten polymer for further processing.
