阅读说明：本技术 液态乙烯共聚物的高压聚合方法 (High pressure polymerization of liquid ethylene copolymers ) 是由 M·温德克尔 I·加西亚卡斯特罗 J·斯特里特马特 K·盖耶 W·格拉巴斯 M·舍尔 R 于 2019-03-14 设计创作，主要内容包括：本发明涉及一种制备液态乙烯共聚物的连续高压聚合方法,所述液态乙烯共聚物以聚合形式包含20-60重量％的乙烯和至少20重量％的丙烯酸酯(其选自(甲基)丙烯酸C<Sub>1</Sub>-C<Sub>22</Sub>烷基酯),其中使包含乙烯和丙烯酸酯的单体进料在至少2重量％的链转移剂存在下聚合。本发明还涉及可通过该聚合方法得到的液态乙烯共聚物；和包含可通过该聚合方法得到的液态乙烯共聚物的润滑剂；和一种用于减少移动表面之间摩擦的方法,该方法包括使表面与润滑剂或与乙烯共聚物接触的步骤。(The present invention relates to a continuous high pressure polymerization process for preparing a liquid ethylene copolymer comprising, in polymerized form, from 20 to 60% by weight of ethylene and at least 20% by weight of an acrylic acid ester selected from (meth) acrylic acid C 1 ‑C 22 Alkyl ester) wherein a monomer feed comprising ethylene and an acrylate is polymerized in the presence of at least 2 wt.% of a chain transfer agent. The invention also relates to a liquid ethylene copolymer obtainable by the polymerization process; and a lubricant comprising a liquid ethylene copolymer obtainable by the polymerization process; and a method for reducing friction between moving surfaces, the method comprising the step of contacting the surfaces with a lubricant or with an ethylene copolymer.)
