ABSTRACT OF THE DISCLOSURE: A process for the manufacture of copoly- mers of ethylene with n-butyl acrylate in a polymerization zone at pressures above 800 atmospheres and at from 150 to 350°C, wherein the reaction mixture obtained is transferred, via a cooling zone which is at a pressure below 500 atmospheres and at from 150 to 250°C, into the high pressure product isolation zone, the mean re- sidence time of the reaction mixture in the two zones being from 2 to 10 minutes. A copolymer which gives good films is obtained.
