PROCESS FOR PRODUCING HOMO AND COPOLYMERS OF ETHYLENE

摘要

A process for producing ethylene polymers or ethylene copolymers comprising the steps of: (a) continuously polymerizing ethylene or ethylene and an alpha -olefin in a reaction mixture at a pressure of at least 300 kg/cm2 and a temperature of at least 130 DEG C. in the presence of a catalyst composed of a compound of a transition metal of groups IVa and VIa of the Periodic Table and an organometallic compound of a metal of groups I to III of the Periodic Table; and (b) adding a polyalkylene glycol to the reaction mixture to deactivate the catalyst.
