HIGH PRESSURE RADICAL ETHYLENE CO POLYMERIZATION PROCESS WITH A REDUCED TEMPERATURE OF THE REACTION MIXTURE PRIOR TO INTRODUCTION INTO THE REACTION ZONE

摘要

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 and R 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.
