Abstract

Ethylene is polymerized under high pressure in an elongated chamber by an intermittent pulse manner as described in U.S.A. Specification 2,852,501, characterized by adjusting the time between pulses according to the "degree-of-plugging" factor of the previous pulse, so that if said factor for the previous pulse is smaller than its predecessor, the time before the next pulse is made longer and vice versa. The "degree-of-plugging" is related to the amount of polymer deposited on the walls of the elongated chamber and is measured by the pressure drop across the reactor.
