| Abstract: | 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. |
