Abstract

Organopolysiloxane sheet or tube polymers are made by contacting a sheet or tube silicate with an alkenyl group containing chlorosilane to form an alkenylsiloxy polymer, and subsequently contacting the alkenylsiloxy sheet or tube polymer with a hydrosilane or hydrosiloxane in the presence of a hydrosilation catalyst, to catalyze a reaction between the alkenyl group on the alkenylsiloxy polymer and hydride functionality on the hydrosilane or hydrosiloxane. Silylalkoxysiloxane sheet or tube polymers are made by contacting a sheet or tube silicate with an acidic solution of an alkenyl alcohol to form a polymeric sheet or tube alkenyloxysiloxane, and subsequently contacting the alkenyloxysiloxane with a hydrosilane or hydrosiloxane in the presence of a hydrosilation catalyst, to catalyze a reaction between the alkenyl group on the alkenyloxysiloxane and hydride functionality on the hydrosilane or hydrosiloxane.
