Abstract: Methods and compositions for encapsulated polymeric gels swollen with nonaqueous reactive materials are provided. The methods include gel synthesis, swelling of a gel precursor with a first nonaqueous reactive material, and encapsulation of the swollen gel with a second nonaqueous reactive material. Gels precursors may be synthesized from crosslinking polymers, or alternatively, may be formed by crosslinking and polymerizing a monomer starting material. An accelerator may be utilized to facilitate swelling of the gel precursor with the first nonaqueous reactive material. Foams and composites may also be swollen with the first nonaqueous reactive material. The swollen gel is then contacted with a second nonaqueous reactive material such that an encapsulation layer is formed thereby. The encapsulated gels may be stored for subsequent use.

Abstract: An effective production method for silane-treated clays having exceptional reinforcing effects with respect to rubber, and compositions using these silane-treated clays are offered. With the silane-treated clay production method, a functional silane is predispersed or emulsified in water by means of a surfactant in order to mix the functional silane with kaolin clay and thereby uniformly surface-treat the kaolin clay with the functional silane. The surfactant should preferably be a non-ionic surfactant with an HLB value in the range of 8-18. The silane-treated clay formed by surface-treating kaolin clay by means of these functional silanes characteristically contains low residual levels of the non-ionic surfactants. The functional silanes can be either vinyl or sulfur functional silanes. The silane treated clays are useful as fillers or extenders in rubber compositions, particularly those employing silicas and/or carbon blacks.
