Abstract: In a process for preparing ethylene-vinyl acetate copolymers in which a mixture of ethylene and vinyl acetate is polymerized continuously in the presence of free-radical polymerization initiators and, if desired, molecular weight regulators in a cooled tube reactor at a pressure in the range from 1000 to 3500 bar, and the poly-merization initiator is added at the beginning and at two or more points along the tube reactor, and temperature changes in the reaction mixture along the tube reactor, between the first temperature maximum and the last addition of the polymerization initiator, are within a range of not more than 20° C.

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.
