Polymerization of N-Phenylmaleimide Catalyzed by (ArO)2Sm(THF)4 王耀荣1,沈琪1,邓明宇1 (1.Department of Chemistry and Engineering, Suzhou University,) Abstract:N-phenylmaleimide was successfully polymerized by divalent samarium complex (ArO)2Sm(THF)4(ArO=2,6-ditertbutyl-4-methyl-phenoxo-). The results show that the conversion of polymerization is higher in THF than in other solvents and increases......
