Abstract: A PROCESS FOR PREPARING ETHYLENE POLYMERS BY PASSING ETHYLENE THROUGH A REACTOR UNDER POLYMERIZATION CONDITIONS IS DISCLOSED, WHEREIN PERIODICALLY THE POLYMERIZATION IS REDUCED OR INTERRUPTED, WHILE PASSSAGE OF ETHYLENE GAS THROUGH THE REACTOR IS MAINTAINED, WHEREBY POLYETHYLENE DEPOSITED ON THE REACTOR WALLS IS DISSOLVED. HIGHER ETHYLENE CONVERSION IS OBTAINED AND THE RISK OF AN EXPLOSIVE DECOMPOSITION OF ETHYLENE IS REDUCED.
