| 摘要 |
A process for preparing a modified polyalkylene, preferably polyethylene or polypropylene, polymer product is described. The process involves treating the polymer in an impregnation step with UV radiation in the presence of a carbonyl bearing photoinitiator species and a crosslinking species. The radiation may take place in a gaseous or liquid environment which is substantially free of oxygen gas but which comprises at least one of the species.
