Abstract

Process for the production of an ethylene/vinyl ester copolymer, with a molecular weight of 500 to 10,000 and intrinsic viscosities of 0.1 to 0.5 dl/g, determined in p-xylene at 25º c, characterized in that it comprises radically polymerizing ethylene and vinyl ester at a temperature of 10 to 200ºC and at a pressure of 10 to 700 bar, in the presence of 0.2 to 5% by weight of acetaldehyde, based on the amount of the initial monomers.
