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 R1 and R2, 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.
