A novel ordered reactive oligomeric ladderlike copolymethyl-aminopropylsilsesquioxane (Me-AP-T), was successfully synthesized by an efficient hydrosilylation graft reaction of 1,1,1-trimethyl-N-2-propenyl-silanamine with a reactive oligomeric ladderlike copolymethyl-hydrosilsesquioxane (Me-H-T), which was prepared by “supramolecular chemistry-dictated stepwise coupling polymerization” process. FT-IR, 1H- and 29Si-NMR spectra show that hydrosilylation reaction proceeds completely. Moreover, 1H-NMR spectra also indicate that both the molar ratios of ≡SiMe group to Si―H and ≡SiMe group to ≡SiPrNH2 are approximately 1:1 respectively based on the ratio of integrated resonance areas of the different groups. XRD analysis and 29Si-NMR spectra are used for investigating the ladderlike structure of the polymers. A high Tg (128.38℃) of Me-AP-T shown in DSC measurement implies that the ordered reactive Me-AP-T macromolecules have much stiff chains.
