Abstract

Oligomethylhydridosiloxane and tis copolymer with dimethylsiloxane undergo redistribution chemistry with catalytic tetrabutylammonium hydroxide (TBAH) to produce methylsilane and polymethylsilsesquioxanes. The rate and extent of redistribution reaction can be controlled by the amount of TBAH added, as well as use of solvent. The extent reaction can be followed by both infrared radiation (IR) and solid state NMR spectroscopy, following the disappearance of the SiH in the starting oligosiloxane.
