    摘要： A thin drywall board that includes a gel coat, at least one polymer/gypsum layer, and a wet glass fiber layer is provided. The gel coat is formed of a gel coat composition that includes a water dispersible polymer, gypsum, and optionally a crosslinking agent and/or a coupling agent. The polymer/gypsum layer is formed of a matrix composition that includes a water dispersible polymeric resin and gypsum. Components including melamine formaldehyde, a filler material, coupling agents, acetic acid, an accelerator, and/or a hardener may also be added to the matrix composition. The wet glass fiber layer is preferably a glass fiber mat. The combination of the water dispersible polymeric resin and the gypsum in the matrix composition have a synergistic effect that creates a thin drywall board that is water resistant, fire resistant, and has improved mechanical properties. A method of forming the inventive thin drywall boards is also provided.

    摘要： Citrate ester compositions which are useful as compatible components in a resinous system for sheet molding compositions and have a general formula ##STR1## wherein X is selected from the group consisting of --OC.sub.3 H.sub.6).sub.3 --OCH.sub.3 and OH are disclosed. Also disclosed is a sheet molding composition which includes a four component resinous system comprising (a) an unsaturated polyester comprising a polycondensation product of one or more dihydric alcohols and one or more ethylenically unsaturated polycarboxylic acids; (b) one or more low-profile thermoplastic polymer additives which cause phase separation and internal voids during the curing reaction; (c) one or more olefinically unsaturated monomers which copolymerize with the unsaturated polyester; and, (d) one or more compatible components which remain compatible when the polyester and monomer cure and impart improved surface characteristics when added to typical low-profile resin systems.

    摘要： A composite material containing wet chopped strand fibers, gypsum, and a polymer material is provided. The wet fibers are filamentized within the polymer material. In exemplary embodiments, the wet chopped strand fibers are wet-used chopped strand glass fibers. The gypsum may be α-gypsum, β-gypsum, or combinations thereof. In at least one embodiment, the polymer is a urea-formaldehyde resin. The composite material may contain a facing layer on at least one exposed major surface of the composite material. A method of forming a composite material that includes mixing gypsum with a polymer material to form a substantially homogeneous matrix and adding a sufficient quantity of wet-used chopped strand fibers to form the composite material is also provided.
