抄録

Vinyl-functionalized cubic silsesquioxanes were prepared from octakis(dimethylsiloxy)octasilsesquioxane via hydrosilylation with 6, 5, and 4 equiv. of allylbenzene followed by the reaction with excess 1,5-hexadiene. The content of hexenyl groups in the silsesquioxanes was determined by ¹H NMR and MALDI-TOF MS. Polyaddition by hydrosilylation of these compounds with bis(dimethylsilyl)benzene afforded polymers with moderate molecular weight soluble in common organic solvents. Chemical structure and thermal stability of the polymers were characterized by NMR, IR, and TGA.
