摘要
发现二价稀土配合物二 ( 2 ,6 二叔丁基 4 甲基苯氧基 )钐 [(ArO) 2 Sm (THF) 4]能较好地引发N 苯基马来酰亚胺 (N PMI)的聚合 ,溶剂对聚合的影响较大 ,在四氢呋喃中聚合转化率最高 ,且聚合转化率随单体浓度的提高而提高 ,而温度对聚合的影响不大。
N phenylmaleimide was successfully polymerized by divalent samarium complex (ArO) 2Sm(THF) 4(ArO=2,6 ditertbutyl 4 methyl phenoxo ). Experimental data shows that the conversion of polymerization is higher in THF than in other solvents and increases with increasing the monomer concentration. The temperature has no obvious effect on the polymerizing process.
