  unsaturated esters. Once the double‐bond is in conjugation with the carboxylate group, they also catalyze the Michael addition of carbon and nitrogen nucleophiles. In the presence of these catalysts, unsaturated carboxylates enter a dynamic equilibrium of positional and geometrical double‐bond isomers. The conjugated species are continuously removed through 1,4‐additions with formation of β‐amino esters or

  发现亚磷酸铑催化剂可有效介导不饱和酯内的双键迁移。一旦双键与羧酸酯基结合，它们还将催化碳和氮亲核试剂的迈克尔加成。在这些催化剂的存在下，不饱和羧酸盐进入位置和几何双键异构体的动态平衡。根据所使用的亲核试剂，通过1,4加成不断地除去结合物，形成β-氨基酯或β-芳基化产物。证明了这两种方案对一系列底物的适用性，例如不同链长和双键位置的脂肪酸酯，以及包括芳基硼酸酯和伯胺和仲胺在内的几种亲核试剂。

  The present invention is intended to provide a polar group-containing olefin copolymer having excellent adhesion properties to metals or polar resins and excellent compatibility therewith, a process for preparing the copolymer, a thermoplastic resin composition containing the copolymer, and uses thereof. The polar group-containing olefin copolymer comprises a constituent unit derived from an α-olefin of 2 to 20 carbon atoms, and a constituent unit derived from a straight-chain, branched or cyclic polar group-containing monomer having at the end a polar group such as a hydroxyl group or an epoxy group and/or a constituent unit derived from a macromonomer having at the end a polymer segment obtained by anionic polymerization, ring-opening polymerization or polycondensation. The polar group-containing olefin copolymer can be prepared by polymerizing the α-olefin with the polar group-containing monomer and/or the macromonomer in the presence of a metallocene catalyst. The polar group-containing olefin copolymer and the thermoplastic resin composition containing the copolymer are used for films, sheets, modifiers, building/civil engineering materials, automobile exterior trim, electric/electronic parts, coating bases, compatibilizing agents, etc.
