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, characterized in that a polyunsaturated olefin grade is used as a starting material which yields a percentage of less than 6.3% in the zero conversion test or which has a decomposition temperature as measured by DSC of 130° C. or more.
