Abstract

PURPOSE: To prepare ethylenic polymer having an improved otpical properties safely and economically by carrying out a high-pressure polymerization reaction in the presence of an antistatic agent in the polymer system.
CONSTITUTION: Polymerization reactions are carried out in the presence of an antistatic agent in the polymer system when ethylenic polymer is prepared from ethylene or a mixture of ethylene and a monomer which is polymerizable with ethylene at a pressure of 500W3500kg/cm2 in a tank reactor or tubular reactor. The mechanism in which the antistatic agent prevents ethylenic polymer from adherting and accumulating to the wall of the reactor is considered that the antistatic agent vanishes static electricity which is generated by a high-speed stream of a mixture of ethylene and ethylenic polymer having a low electric conductivity.
