| 英文摘要 | A highly ordered m-phenylenedfirnino-bridged ladder polyhydrosiloxane (abbr. OLPHS) with M-n = 1.24 x 10(4) was synthesized under assistance of H-bonding template constructed from imino H-bonding, N(Si)-H... N(Si)-H, via a modified process of stoichiometric hydrolysis and dehydrochlorination condensation reaction between Si-Cl and Si-OH bonds. The complete ladder structure of OLPHS has been confirmed by the following three data. Two characteristic Bragg's peaks representing the ladder width (w = 0.94 nm) and ladder thickness (t = 0.42 nm) were observed in XRD analysis, which are consistent with those calculated by molecular simulation. The very sharp absorption with a small half-peak width (w(1/2) = 0.5 ppm) for [(-HN)HSiO2/2](n) moiety of OLPHS in Si-29 NMR spectrum indicated presence of the complete ladder structure. As collateral evidence, a higher glass transition temperature (Tg = 105 degrees C) is also recorded in the DSC measurement, implying the high stiffness of ladder chain of OLPHS.
