研究了(CF_3COO)_2NdCl·EtOH—Et_3Al均相催化剂体系在9种溶剂中的双烯烃聚合。结果表明,聚合活性和聚合物特性粘数不但与溶剂的介电常数有关,而且与溶剂的其它性质有关;聚合物的微观结构不受溶剂种类的影响。并用溶剂参与催化剂活性中心作用讨论了试验结果。
The copolymerization of (CF_3COO) _2NdCl · EtOH-Et_3Al homogeneous catalyst system in 9 solvents was studied. The results show that the polymerization activity and intrinsic viscosity of the polymer are not only related to the dielectric constant of the solvent, but also related to other properties of the solvent. The microstructure of the polymer is not affected by the solvent type. The effects of solvent on the active site of catalyst were discussed.
