Abstract

The present invention relates to a high-pressure radical ethylene polymerization process in which ethylene is polymerized with - a polyunsaturated olefin comprising at least 6 carbon atoms and at least two non-conjugated double bonds of which at least one is terminal; and/or - an alpha-omega-divinylsiloxane according to Formula I wherein R 1 and R 2 , which can be alike or different, are selected among alkyl groups having 1-4 carbon atoms and alkoxy groups having 1-4 carbon atoms, and n is 1-200, characterized in that the maximum temperature of the reaction mixture prior to introduction into the reaction zone is 160 °C or less.
