摘要:
Articles of manufacture, such as bulk composites, composite coatings, and composite films, can be prepared by exposing a gel to air, and allowing it to stand at room temperature to cure. The gel is obtained by mixing an organopolysiloxane sheet or tube polymer with an alkoxysilane. Organopolysiloxane sheet or tube polymers are obtained by contacting sheet or tube silicates with an organohalosilane and a solvent, and heating the mixture.

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.
摘要:
Consumer product compositions such as laundry detergents comprising selected photosensitive compounds for photobleaching, photodisinfection, antibacterial activity, hueing or other benefits. The compositions are preferably formulated with detersive surfactants and/or water-soluble polymers.
