[CyNC(CH_3)NCy]_3La催化N-苯基马来酰亚胺聚合

Polymerization of N-phenylmaleimide catalyzed by [CyNC(CH_3)NCy]_3La

均配型脒基镧[CyNC(CH3)NCy]3La(Cy=环己基)能较好地引发N-苯基马来酰亚胺(N-PMI)的聚合,并且聚合转化率随催化剂与单体的摩尔浓度比的提高而增加,而温度对聚合的影响不大.

N-phenylmaleimide was successfully polymerized by homoleptic lanthanum amidinate complex [CyNC（CH3）NCy]3La.The polymerization activity increases with increase of the molar ratio of the catalyst to the monomer,and is hardly dependent on the polymerization temperature.
