  Synthesis of Substituted Cyclooctanols by a Samarium(II) Iodide Promoted 8-Endo Radical Cyclization Process

  摘要：

  Samarium(II) iodide (SmI2) has been employed to promote an efficient 8-endo radical cyclization reaction of a variety of substituted olefinic ketones. Various substituted monocyclic, fused bicyclic, and bridged bicyclic cyclooctanols have been synthesized in fair to excellent yield via this protocol. In addition to delineating the synthetic potential of this reaction, experiments have been conducted to determine the source of reduced, noncyclized byproducts present in this and related SmI2-mediated reactions performed under protic conditions.

  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.

  本发明旨在提供一种对金属或极性树脂具有极佳粘附性和相容性的含极性基团的烯烃共聚物、制备该共聚物的工艺、含有该共聚物的热塑性树脂组合物及其用途。含极性基团的烯烃共聚物包括一个由 2 至 20 个碳原子的 α-烯烃衍生的组成单元和一个由直链、支链或环状含极性基团单体衍生的组成单元，直链、支链或环状含极性基团单体的末端具有极性基团，如羟基或环氧基，和/或一个由大单体衍生的组成单元，大单体的末端具有通过阴离子聚合、开环聚合或缩聚反应获得的聚合物段。含极性基团的烯烃共聚物可通过在茂金属催化剂存在下使α-烯烃与含极性基团的单体和/或大单体聚合来制备。含极性基团的烯烃共聚物和含有该共聚物的热塑性树脂组合物可用于薄膜、板材、改性剂、建筑/土木工程材料、汽车外饰、电气/电子零件、涂层基料、相容剂等。
