Abstract

Perfluoroalkyltrialkoxysilanes were prepared by hydrosilylation of the allylic or vinylic derivatives with trialkoxysilane or with trichlorosilane (followed by a quantitative methanolysis). The hydrolysis and polycondensation of these precursors were performed in the presence of tetrabutylammoniumfluoride (TBAF) as the catalyst, leading to a series of new polysilsesquioxanes, which were characterized by solid state 13C and 29Si CPMAS ...
