Abstract
A continuous process for producing polyethylene or copolymers of ethylene with other copolymerizable compounds at a pressure of at least 1,000 kg/cm.sup.2 in a tubular reactor under steady conditions without imposing on the polymerization system flow pulses, while keeping the monomer conversion at 35% or lower and the melt index of the polymer at 0.1 or more.
