聚合负载三氯化钕配合物的合成及其催化活性—含硫醇和亚砜基团的配合物

Synthesis and Catalytic Activities of Polymer-Supported Neodymium Complexes —Polymers Containing Thiol and Sulphoxide

合成了含—CH2 SH和—CH2 SOCH3 功能团的交联聚苯乙烯钕配合物P—CH2 SH·NdCl3 和P—CH2 SOCH3·NdCl3。P—CH2 SH·NdCl3 对丁二烯聚合没有催化活性 ,而P—CH2 SOCH3·NdCl3 可使丁二烯高顺式聚合 ,聚丁二烯顺 1,4单元含量在 95 %以上。

The complexes (P—CH 2SH·NdCl 3 and P—CH 2SOCH 3·NdCl 3) of crosslinked polystyrene containing —CH 2SH and —CH 2SOCH 3 groups were prepared. The P—CH 2SH·NdCl 3 shows no catalytic activity for butadiene polymerization, while P—CH 2SOCH 3·NdCl 3 catalyzes the polymerization of butadiene. The content of cis 1,4 polybutadiene is more than 95%.
