Abstract

A dilute suspension of ethylene in water is polymerized in the presence of a peroxide initiator or an azo compound at a temperature of from 10 DEG to 100 DEG C. and a pressure from 100 to 1000 Kg./cm.2, the reaction medium including from 0.001 to 2% of a surfactant by weight of water and the reaction being performed for 1/2 to 8 hours. The initiator is preferably a dialkyl percarbonate and the surfactant a nonionic surfactant. The medium may contain a long-chain alcohol as micelle modifier. The reaction can be carried out by recycling the reagents.
