Abstract: Soy-based high temperature products, or thermoset resins, are produced by solvent free polymerization of soy polyols and polyisocyanates at room temperature. The ratio of isocyanate equivalents to polyol equivalent used in the synthesis is greater than or equal to 3. The invented soy-based products are polyisocyanurate solid materials with excellent stability at high temperature. Heat resistance of the material is influenced by ratio of soy polyol and polyisocyanate.

Abstract: A one component moisture-curing polyurethane adhesive composition having a long pot life that does not cause its user to experience breathing difficulty is described. In one embodiment the adhesive is prepared from a mixture of a high molecular weight component selected from the group consisting of polyols, diamines, and mixtures thereof; an isocyanate; and a low molecular weight component selected from the group consisting of diols, diamines, and mixtures thereof.

Abstract: A photopolymerization method is disclosed for attaching a chemical microsensor film to an oxide surface including the steps of pretreating the oxide surface to form a functionalized surface, coating the functionalized surface with a prepolymer solution, and polymerizing the prepolymer solution with ultraviolet light to form the chemical microsensor film. The method also allows the formation of molecular imprinted films by photopolymerization. Formation of multilayer sensing films and patterned films is allowed by the use of photomasking techniques to allow patterning of multiple regions of a selected sensing film, or creating a sensor surface containing several films designed to detect different compounds.
