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 ~(29)Si-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≡SiPrNH_2 are approximately 1:1 respectively based on the ratio of integrated resonance areas of the different groups.XRD analysis and ~(29)Si-NMR spectra are used for investigating the ladderlike structure of the polymers.A high T_g(128.38℃)of Me-AP-T shown in DSC measurement implies that the ordered reactive Me-AP-T macromolecules have much stiff chains.
A novel ordered reactive oligomeric ladderlike copolymethyl-aminopropylsilsesquioxane (Me-AP-T), was synthesized by an efficient hydrosilylation graft reaction of 1,1,1-trimethyl-N-2-propenyl-silanamine with a reactive oligomeric ladderlike copolymethyl-hydrosilsesquioxane (Me-HT), which was prepared by “supramolecular chemistry-dictated stepwise coupling polymerization” process. FT-IR, ~ 1H- and ~ (29) Si-NMR spectra show that hydrosilylation reaction transfe completely. spectra also indicate that both of the molar ratios of ≡SiMe group to Si-H and ≡SiMe group to ≡SiPrNH_2 are approximately 1: 1 respectively based on the ratio of integrated resonance areas of the different groups. XRD analysis and ~ (29) Si -NMR spectra are used for investigating the ladderlike structure of the polymers. A high T_g (128.38 ° C) of Me-AP-T shown in DSC measurement implies that ordered reactive Me-AP-T macromolecules have much stiff chains.
