| 发明名称 | High-pressure radial ethylene polymerization process in which ethylene is polymerized with a specific polyunsaturated olefin grade | ||
| 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. | ||

| 主权项 | 1. 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, wherein a zero conversion test is carried out on a polyunsaturated olefin grade at 200 Mpa and 230° C. and a polyunsaturated olefin grade which yields a percentage of less than 6.3% in the zero conversion test is used as a starting material. | ||
