1. A method of bonding a first material to a second material, comprising the steps of: (a) applying an adhesive foam to a first material to give an adhesive coated mating surface;(b) applying a second material to said adhesive coated mating surface of said first material; and(c) applying temporarily
1. A method of bonding a first material to a second material, comprising the steps of: (a) applying an adhesive foam to a first material to give an adhesive coated mating surface;(b) applying a second material to said adhesive coated mating surface of said first material; and(c) applying temporarily a casting surface to said adhesive coated mating surface,wherein said second material is a foam prepared from water and a prepolymer mixture selected from the group consisting of branched alkyl-isocyanate-capped poly(ether), unbranched alkyl-isocyanate-capped poly(ether), branched aromatic-isocyanate-capped poly(ether), unbranched aromatic-isocyanate-capped poly(ether), branched alkyl-isocyanate-capped poly(ether)-poly(ester) copolymer, unbranched alkyl-isocyanate-capped poly(ether)-poly(ester) copolymer, branched aromatic-isocyanate-capped poly(ether)-poly(ester) copolymer, and unbranched aromatic-isocyanate-capped poly(ether)-poly(ester) copolymer; andsaid adhesive foam is a foam prepared from water and a prepolymer mixture selected from the group consisting of branched alkyl-isocyanate-capped poly(ether), unbranched alkyl-isocyanate-capped poly(ether), branched aromatic-isocyanate-capped poly(ether), unbranched aromatic-isocyanate-capped poly(ether), branched alkyl-isocyanate-capped poly(ether)-poly(ester) copolymer, unbranched alkyl-isocyanate-capped poly(ether)-poly(ester) copolymer, branched aromatic-isocyanate-capped poly(ether)-poly(ester) copolymer, and unbranched aromatic-isocyanate-capped poly(ether)-poly(ester) copolymer. 2. The method of claim 1, wherein said casting surface is a paper, polymeric film, or polyurethane foam. 3. A method of bonding a first material to a second material, comprising the steps of: (a) applying an adhesive foam to a first material to give an adhesive coated mating surface;(b) applying a second material to said adhesive coated mating surface of said first material;(c) separating said second material from said first material before said adhesive is completely cured; and(d) applying a third material and a fourth material to said first and second materials, respectively,wherein said second material is a foam prepared from water and a prepolymer mixture selected from the group consisting of branched alkyl-isocyanate-capped poly(ether), unbranched alkyl-isocyanate-capped poly(ether), branched aromatic-isocyanate-capped poly(ether), unbranched aromatic-isocyanate-capped poly(ether), branched alkyl-isocyanate-capped poly(ether)-poly(ester) copolymer, unbranched alkyl-isocyanate-capped poly(ether)-poly(ester) copolymer, branched aromatic-isocyanate-capped poly(ether)-poly(ester) copolymer, and unbranched aromatic-isocyanate-capped poly(ether)-poly(ester) copolymer;said adhesive foam is a foam prepared from water and a prepolymer mixture selected from the group consisting of branched alkyl-isocyanate-capped poly(ether), unbranched alkyl-isocyanate-capped poly(ether), branched aromatic-isocyanate-capped poly(ether), unbranched aromatic-isocyanate-capped poly(ether), branched alkyl-isocyanate-capped poly(ether)-poly(ester) copolymer, unbranched alkyl-isocyanate-capped poly(ether)-poly(ester) copolymer, branched aromatic-isocyanate-capped poly(ether)-poly(ester) copolymer, and unbranched aromatic-isocyanate-capped poly(ether)-poly(ester) copolymer; andsaid third material and said fourth material are independently cotton, wool, silk, jute, linen, rayon, acetate, polyesters, polyethyleneterephthalate, polyamides, nylon, acrylics, olefins, aramids, azlons, glasses, fiberglass, modacrylics, novoloids, nytrils, rayons, sarans, spandex, vinal, vinyon, foams, films, foamed sheets, natural leathers, split hides, synthetic leathers, vinyl, urethane, polyurethane foam, polyurethane film, polyethylene, polymeric silicone layers, filtration membranes, polysulfones, polyimides, nitrocellulose, cellulose acetate, cellulose, regenerated cellulose, alginates, hydrocolloids, metalized films, foils, silicones, latex, polycarbonates, or a foam prepared from water and a prepolymer mixture selected from the group consisting of branched alkyl-isocyanate-capped poly(ether), unbranched alkyl-isocyanate-capped poly(ether), branched aromatic-isocyanate-capped poly(ether), unbranched aromatic-isocyanate-capped poly(ether), branched alkyl-isocyanate-capped poly(ether)-poly(ester) copolymer, unbranched alkyl-isocyanate-capped poly(ether)-poly(ester) copolymer, branched aromatic-isocyanate-capped poly(ether)-poly(ester) copolymer, and unbranched aromatic-isocyanate-capped poly(ether)-poly(ester) copolymer. 4. A method of bonding a first material to a second material, comprising the steps of: (a) applying an adhesive foam to a first material to give an adhesive coated mating surface;(b) applying a second material to said adhesive coated mating surface of said first material; and(c) applying a third material to said second material,wherein said second material is a foam prepared from water and a prepolymer mixture selected from the group consisting of branched alkyl-isocyanate-capped poly(ether), unbranched alkyl-isocyanate-capped poly(ether), branched aromatic-isocyanate-capped poly(ether), unbranched aromatic-isocyanate-capped poly(ether), branched alkyl-isocyanate-capped poly(ether)-poly(ester) copolymer, unbranched alkyl-isocyanate-capped poly(ether)-poly(ester) copolymer, branched aromatic-isocyanate-capped poly(ether)-poly(ester) copolymer, and unbranched aromatic-isocyanate-capped poly(ether)-poly(ester) copolymer;said adhesive foam is a foam prepared from water and a prepolymer mixture selected from the group consisting of branched alkyl-isocyanate-capped poly(ether), unbranched alkyl-isocyanate-capped poly(ether), branched aromatic-isocyanate-capped poly(ether), unbranched aromatic-isocyanate-capped poly(ether), branched alkyl-isocyanate-capped poly(ether)-poly(ester) copolymer, unbranched alkyl-isocyanate-capped poly(ether)-poly(ester) copolymer, branched aromatic-isocyanate-capped poly(ether)-poly(ester) copolymer, and unbranched aromatic-isocyanate-capped poly(ether)-poly(ester) copolymer;said second material is permeable to said adhesive foam; andsaid third material is a foam prepared from water and a prepolymer mixture selected from the group consisting of branched alkyl-isocyanate-capped poly(ether), unbranched alkyl-isocyanate-capped poly(ether), branched aromatic-isocyanate-capped poly(ether), unbranched aromatic-isocyanate-capped poly(ether), branched alkyl-isocyanate-capped poly(ether)-poly(ester) copolymer, unbranched alkyl-isocyanate-capped poly(ether)-poly(ester) copolymer, branched aromatic-isocyanate-capped poly(ether)-poly(ester) copolymer, and unbranched aromatic-isocyanate-capped poly(ether)-poly(ester) copolymer. 5.
