【摘要】 <正> The hydrosilylation reaction of ladderlike polyvinylsilsesquioxane （Vi-T）with 1, 1, 3, 3-tetramethyldisiloxane （H- MM ） catalyzed by dicyclopentadienyl-dichloroplat-inium （Cp₂PtCl₂） was carried out well in tetrahydrofuran （THF） to produce a soluble whitesolid. This product was characterized by IR, ¹H-NMR, ¹³C-NMR, ²⁹Si-NMR, DSC, X-raydiffraction method, gel permeation chromatography （GPC）, vapour pressure osmometry（VPO）, atomic force microscopy （AFM） and molecular simulation. These results provethat the product contains nanoscale tubular structure.更多还原
