Abstract: The invention relates to a method for producing ethylene/vinyl acetate copolymers in which a mixture comprised of ethylene and vinyl acetate is continuously polymerized in the presence of radical polymerization initiators and optional molecular weight modifiers in a cooled tubular reactor at a pressure ranging from 1000 to 3500 bar. The polymerization initiator is charged at the beginning and at a number of positions along the tubular reactor, and the temperature changes i n the reaction mixture range no more than 20.degree.C between the first maximum temperature and the last charging of the polymerization initiator along the tubular reactor.
