    摘要: A method for synthesizing an apophyllite-derived 3-cyanopropyldimethylsiloxy-5-hexenyldimethylsiloxy sheet polymer (A-CM.sub.2 -HEM.sub.2); an apophyllite-derived 3-cyanopropyldimethylsiloxy-vinyldimethylsiloxy sheet polymer (A-CM.sub.2 -VM.sub.2); and an apophyllite-derived 3-cyanopropyldimethylsiloxy-n-decyldimethylsiloxy sheet polymer (A-CM.sub.2 -DM.sub.2). These polymers form gels with simple polar solvents such as acetone and therefore can be easily processed. The first two of the polymers, i.e., A-CM.sub.2 -HEM.sub.2 and A-CM.sub.2 -VM.sub.2, form gels with polar solvents carrying olefinic linkages, and these gels can be crosslinked into sheet composites having fully exfoliated organosilicon sheets in an organic matrix.

    摘要: Gels, cast films, coatings, extruded rods, extruded fibers, compression molded discs, and machined compression molded discs, are made from organopolysiloxane sheet or tube polymers such as an apophyllite-derived 3-cyanopropyldimethyl siloxy sheet polymer of the formula [((NCC.sub.3 H.sub.6)(CH.sub.3).sub.2 SiO).sub.x (HO).sub.1-x SiO.sub.1.5 ].sub.n. Polymers are prepared by contacting sheet or tube silicates with an organohalosilane containing at least one polar group such as cyanoalkyl, acyloxy, or haloalkyl, in the presence of a polar solvent or a mixture of a polar solvent and a non-polar solvent; and heating the mixture until a polymer is formed.
