报道了一种合成主链含有冠醚基团的聚硅氧烷的方法.首先,从适当的冠醚出发,合成带有两个烯基侧链的双套索冠醚,再与含氢硅单体进行硅氢加成.合成两端带有烷氧硅基的含冠醚基的硅单体,然后与八甲基环四硅氧烷共聚合,得到标题聚硅氧烷.后者与氯亚铂酸钾反应,得到相应的铂配合物,该配合物对于烯烃与三乙氧基硅烷的硅氢加成反应具有催化活性.

A new type of crown ether functionalized polysiloxane, in which the crown moieties were incorporated into the main chain, and its platinum complex were prepared from 3,19-dihydroxy-1-thia-5,8,11,14,17-pentaoxacycloicosane via etherification with w-chloroundecene, followed by hydrosilylation with triethoxysilane, copolymn. with octamethylcyclotetrasiloxane and then reacting with potassium chloroplatinite. The catalytic behavior of the platinum complex in the hydrosilylation of olefins with triethoxysilane has been studied.
