  摘要：

  2-环丙基-2-重氮乙酸甲酯是由乙酰环丙烷通过几个化学步骤合成的，总产率约 55%。其铜或铑催化的脱重氮反应仅通过生成的环丙基（甲氧基羰基）卡宾分子内异构化为1-甲氧基羰基环丁烯进行，无论是否存在不饱和化合物。然而，在丙烯酸酯或应变环烯烃的存在下，这种重氮酯缓慢参与1,3-偶极环加成反应，得到环丙基取代的吡唑啉甲酸酯，在1-吡唑啉的情况下，它很容易失去氮分子，选择性地生成1-环丙基环丙烷甲酸酯衍生物。

  The present invention relates to high performance wire and cable compositions and to hot melt adhesives containing a silyl-grafted ethylene copolymer having particularly low levels of glycidyl acrylate monomer. The preferred epoxy glycidyl methacrylate copolymerized into the polymer backbone provides a graft site for the aminosilane. Subsequent moisture crosslinking at the silyl site of the thermally stable graft copolymer provides compositions with attractive physical properties for wire and cable semicons, insulation, and jackets, as well as hot melt adhesives. The preferred aminosilane is N-cyclohexylaminopropyl trimethoxysilane.

  Disclosed is a process for esterifying and/or transesterifying a polymer having a polyethylenic backbone and pendant acid and/or ester moieties comprising contacting a melt of the polymer with a transesterifying compound so that the polymer undergoes esterification and/or transesterification but not alcoholysis. The esterified or transesterified polymer also has pendant ester moieties which differ in kind and/or number from the unreacted polymer. In one embodiment, the process also comprises adding an amount of a transition metal salt that is effective to promote oxygen scavenging. Also in a further embodiment, the process comprises irradiating the transesterified polymer with actinic radiation to reduce the induction period before oxygen scavenging commences. Also disclosed are compositions comprising a component which comprises an ethylenic or polyethylenic backbone and a pendant or terminal moiety comprising a benzylic, allylic, or ether-containing radical. The invention also embodies new polyethylenic oxygen scavenging compositions comprising a transition-metal salt and the above component. Methods of making the compositions, and methods and compositions using the ethylenic or polyethylenic compositions, are disclosed.
