摘要
合成了含-CH2SH和-CH2SOCH3功能团的高分子载体氯化稀土配合物P—CH2SHNdCl3和P-CH2SOCH3·NDCl3.P-CH2SH·NDCl3对丁二烯聚合没有催化活性,P-CH2SOCH3·NdCl3对丁二烯聚合有催化活性.其催化体系有很高的定向效应,聚丁二烯顺-1,4结构含量在95%以上。
s:Neodymium complexes with crosslinded polystyrene having pendant-CH2SH anb CH2SOCH3 groups haye been prepared and characterized P-CH2SH·NdCl3 system showed noactivity for butadiene polymerization while P-CH2SOCH3·NdCl3 can polymerize butadiene to high cispolymer.The content of cis-1,4 polybutadiene was more than 95%.
