ABSTRACT:
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.
