    • In the polymerization, in which an aqueous phase is employed, of ethylene, or ethylene and other unsubstituted or substituted olefinic monomers by means of an ionizing radiation, formation of an undesirable polymer in the aqueous phase of the reaction system is inhibited by using specific polymerization inhibitors. The inhibitors which have no adverse effect on the polymerization in the non-aqueous phase, comprise the electrolytes which have strong oxidizing action and/or react at high reaction rate with active species such as H radicals, OH radicals and/or hydrated electrons formed by ionizing radiation. According to the present invention, adhesion of undesirable polymer to the reactor walls during polymerization reaction is prevented and contamination which lowers the quality of the main polymer is eliminated.
    • 在使用水相的乙烯或乙烯和其它未取代或取代的烯属单体的聚合中,通过电离辐射,在反应体系的水相中形成不需要的聚合物通过使用特定的聚合来抑制 抑制剂。 对非水相中的聚合没有不利影响的抑制剂包括具有强氧化作用和/或以高反应速率与活性物质如H自由基,OH自由基和/或水合电子反应的电解质, 电离辐射。 根据本发明,防止了聚合反应期间不期望的聚合物对反应器壁的粘附,并且消除了降低主聚合物质量的污染。
