<正> A modified method of preparing crown functionalized linear polysiloxane has been described.4’-allylbenzo-15-crown-5 was subjected to hydrosilylation with methyldichlorosilane
followed bypolycondensation with silanol-terminated polydimethylsiloxane to give the title crownfunctionalized linear polysiloxane. It was found that the polysiloxane could be coordinated withplatinum salt to form platinum complex
which could catalyze the hydrosilylation of olefins withtriethoxysilane efficiently.
