    摘要： A process for polymerizing ethylene at a high temperature under high pressure, which comprises contacting ethylene alone or along with an .alpha.-olefin at a temperature of 120.degree. C. or more at a pressure of 350 kg/cm.sup.2 or more with a catalyst consisting essentially of (A) a reaction product of (A1) a titanium compound having at least one titanium-nitrogen bond with (A2) an organometallic compound of an element of Groups I to III of the Periodic Table and (B) an organoaluminum compound. Said process enables the production of an ethylene polymer or copolymer having a narrow composition distribution and a high molecular weight and being excellent in weather resistance, color development, transparency, corrosiveness and mechanical properties.
