    摘要: A polyacrylic polymer is provided that is formed by moisture cure of multiple acrylic prepolymer segments. The prepolymer segments each have an average molecular weight of between 5000 and 400,000 grams per mole. Each of the prepolymers is a homopolymer or copolymer of a monomer from among methyl methacrylate, C1-C16 alkyl acrylate, and C1-C16 alkyl methyl methacrylate as the predominant monomeric group. The prepolymers are interconnected through moisture cure induced urea, urethane, or combinations thereof. The polymer is readily cured upon exposure to atmospheric moisture absent inclusion or evolution of a volatile organic compound. The polymer is likewise formed HAP free. Through control of prepolymer properties a variety of thermoset polymer properties are obtained. A prepolymer is formed including a minority amount of functionalized acrylic monomer that is isocyanate or converted to isocyanate through subsequent reaction. Functionalized acrylic monomers operative herein include a hydroxyl, a primary amine, a secondary amine, a sulfonic acid, or an epoxy. Upon application from storage in an anhydrous state, the prepolymer cures upon exposure to atmospheric moisture.

    摘要: A moisture curable acrylic formulation is provided inclusive of a majority by weight polyacrylic prepolymer. The prepolymer has an average molecular weight of between 3,000 and 6,000 grams per mole and between 2 and 4 moisture curable functional moieties of isocyanate or silane per prepolymer. A thermoplastic adhesive resin is also included within the formulation. When the prepolymer functional moieties are all silane, the thermoplastic adhesive resin is ethylene vinyl acetate resin. A silane molecule is provided within the formulation as an adhesion promoter and also affords a degree of storage stability through sacrificial reaction with water during storage. The resultant formulation achieves a shear strength of at least 10 pounds per square inch when applied to a thickness of 0.75 millimeters between a glass substrate and a vinyl article 15 minutes after application at 120° Celsius in ambient atmospheric air. The formulation is well suited for the formation of a window assembly when applied intermediate between a substrate and a window article.
