Ladderlike polyhydroxypropylsilsesquioxane (HO-T) was synthesized by alcoho
lysis of ladderlike poly(3-propionyloxy-propyl)silsesquioxane. The HO-T was
characterized by GPC, IR, NMR, DSC, TGA and X-ray diffraction methods. Thr
ough hydrogen-bonding interaction, ladderlike polymer (HO-T) can form a sup
ramolecular complex with somewhat regular structure.
