文摘

A novel soluble aryl amide-bridged ladderlike polymethylsiloxane (A-LPMS) was synthesizedby stepwise coupling polymerization on the basis of amido H-bonding self-assembling template frommonomer N,N'-bis(3-methyldiethoxylsilylpropyl)-[4,4'-oxybis(benzyl amide)]. The monomer was preparedin a high yield by the hydrosilylation reaction of template agent N,N'-diallyl-[4,4'-oxybis(benzyl amide)] withmethyldiethoxysilane in the presence of dicyclopentadienylplatinum dichloride (Cp₂PtCl₂) as catalyst. Avariety of techniques including ¹H NMR, ¹³C NMR, ²⁹Si NMR, FTIR, XRD, DSC, and, especially, static anddynamic light scattering and viscosimetry were combined to confirm the presence of the ordered ladderlikestructure of polymer A-LPMS.
