  CATALYSTS FOR OLEFIN POLYMERIZATION

  摘要：

  选定的单阴离子膦配体的过渡金属配合物，其中还含有选定的第15或16组（IUPAC）元素，并与第3至11组（IUPAC）的过渡金属或镧系金属配位，可用作（共）聚合乙烯和α-烯烃以及这些烯烃与含极性基团的烯烃的共聚合催化剂。这些以及其他中性和单阴离子双齿配体的镍配合物可在相对较高的乙烯压力和出乎意料的高温下共聚合乙烯和极性共聚单体，且极性共聚单体的掺入和聚合产率良好。这些共聚物通常具有独特的结构，已进行描述。

  Transition metal complexes of selected monoanionic phosphine ligands, which also contain a selected Group 15 or 16 (IUPAC) element and which are coordinated to a Group 3 to 11 (IUPAC) transition metal or a lanthanide metal, are polymerization catalysts for the (co)polymerization of olefins such as ethylene and &agr;-olefins, and the copolymerization of such olefins with polar group-containing olefins. These and other nickel complexes of neutral and monoanionic bidentate ligands copolymerize ethylene and polar comonomers, especially acrylates, at relatively high ethylene pressures and surprisingly high temperatures, and give good incorporation of the polar comonomers and good polymer productivity. These copolymers are often unique structures, which are described.
