阅读说明：本技术 至少一种半过氧缩醛单独地或与其它过氧化物组合用于促进在高压下的乙烯的聚合或共聚的用途 (Use of at least one hemiperoxy acetal, alone or in combination with other peroxides, for promoting the polymerization or copolymerization of ethylene at high pressure ) 是由 B.范赫梅尔里克 V.梅嫩托 于 2019-12-18 设计创作，主要内容包括：本发明涉及选自半过氧缩醛的至少一种过氧化物单独地或与一种或多种不同的另外的过氧化物组合用于在高压下的乙烯的自由基聚合或共聚的用途。本发明还涉及制备聚乙烯的方法,该方法包括以下步骤：在单独的或与一种或多种不同的另外的过氧化物组合的选自半过氧缩醛的至少一种过氧化物的存在下,在高压下的乙烯的自由基聚合或共聚。本发明还涉及一种组合物,其包含乙烯、选自半过氧缩醛的至少一种过氧化物、以及任选的不同于半过氧缩醛的一种或多种另外的过氧化物。(The present invention relates to the use of at least one peroxide selected from the group of hemiperoxy acetals, alone or in combination with one or more different additional peroxides, for the radical polymerization or copolymerization of ethylene under high pressure. The invention also relates to a process for preparing polyethylene, comprising the steps of: free-radical polymerization or copolymerization of ethylene under high pressure in the presence of at least one peroxide selected from the group of hemiperoxy acetals, alone or in combination with one or more different additional peroxides. The invention also relates to a composition comprising ethylene, at least one peroxide selected from the group of hemiperoxy acetals, and optionally one or more additional peroxides different from the hemiperoxy acetal.)
