Abstract
A method of making an organopolysiloxane sheet or tube polymer involves contacting a sheet or tube silicate with an organo-H-chlorosilane to form an organosiloxane sheet or tube polymer with pendent .tbd.Si--H groups. Subsequently, the organosiloxane sheet or tube polymer with pendent .tbd.Si--H groups is contacted with an alkenyl group containing compound in the presence of a hydrosilation catalyst. The catalyst is used in an amount effective to catalyze a hydrosilation reaction between the alkenyl group on the alkenyl group containing compound and the hydride functionality on the organosiloxane sheet or tube polymer with pendent .tbd.Si--H groups, to form the organopolysiloxane sheet or tube polymer,
