摘要: 制备了4-乙烯基吡啶-镍(钴)和丙烯酰胺-镍(钴)络合物并研究了它们的结构。在自由基引发剂的作用下,4-乙烯基吡啶-镍可进行溶液聚合,也可与苯乙烯共聚合,测定了单体的竞聚率。所得的聚(4-乙烯基吡啶-镍)及聚(4-乙烯基吡啶-钴)以NaBH_4还原后可作为一些有机化合物的加氢催化剂。由IR及XPS分析说明在丙烯酰胺-镍络合物中,与镍离子发生了络合作用的是羧基上的氧原子。Abstract: 4-vinylpyridine-Ni (Co) and acrylamide-Ni (Co) complexes were prepared and their structures were studied. 4-vinylpyridine-Ni was polymerized and copolymerized with styrene in solut ion with free radical initiator, The monomer reactivity ratios were determ
