摘要： 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. The methods further include release of the first nonaqueous reactive material encapsulated within the gel under conditions which compromise the integrity of the encapsulation layer. The released first nonaqueous reactive material is then reacted with a nonaqueous reactive material, the reaction product being a useful product for a variety of applications such as coatings, adhesives, sealings, caulking, laminating materials, electrical coatings and the like.
