摘要： A cross-linked, responsive polymer gel network comprising polymer chains interconnected by way of a multifunctional cross-linker is described. The polymer chains and cross-linker have a known acceptable toxicological profile (KATP). Pathways for determining if a particular material has a KATP are provided. The polymer chains should be a component part of a product that is considered in compliance with applicable governmental agency regulations as acceptable for a use selected from the group consisting of a food use, a cosmetic use, and an animal drug delivery use. Moreover, the cross-linker also should be a component part of a product that is considered in compliance with applicable governmental agency regulations as acceptable for a use selected from the group consisting of a food use, a cosmetic use, and an animal drug delivery use.

摘要： Methods and compositions for encapsulated polymeric gels swollen with non-aqueous reactive materials are provided. The methods include gel synthesis, swelling of a gel precursor with a first non-aqueous reactive material, and encapsulation of the swollen gel with a second non-aqueous 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 non-aqueous reactive material. Foams and composites may also be swollen with the first non-aqueous reactive material. The swollen gel is then contacted with a second non-aqueous 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 non-aqueous reactive material encapsulated within the gel under conditions which compromise the integrity of the encapsulation layer. The released first non-aqueous reactive material is then reacted with a non-aqueous 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.
