ABSTRACT OF THE DISCLOSURE: A process for the manufacture of ethylene polymers by polymerizing ethylene under high pressures and at high temperatures in the presence of from 0.01 to 0.5 per cent by weight of an alkyl ester (alkyl being of 1 to 8 carbon atoms) of an alkene- monocarboxylic acid of 3 or 4 carbon atoms. n-Butyl acrylate is a particularly suitable polymerization activator. Although the start temperature of the ethylene polymerization is relatively low, there is no difference in mechanical and optical properties of a blown film manufactured from the resulting ethylene polymer and of a blown film of pure polyethylene.
