Abstract: Textile materials, including paper webs, treated with a polyvinylamine polymer and a second agent that interacts with the polyvinylamine polymer is disclosed. The second agent added with the polyvinylamine polymer can be, for instance, a polymeric anionic reactive compound or a polymeric aldehyde-functional compound. When incorporated into a paper web, the combination of the polyvinylamine polymer and the second agent provide improved strength properties, such as wet strength properties. In an alternative embodiment, the polyvinylamine polymer and the second polymer can be applied to a textile material for increasing the affinity of the textile material for acid dyes.
Abstract: Enhanced tear strength asphalt roofing composites, e.g., roofing shingles which can meet the current ASTM D-3462 standard for tear strength, include an adhesion modifier treated, preferably a polysiloxane treated, glass fiber mat.

Abstract: A crosslinkable cellulosic fibrous product that includes cellulosic fibers and a crosslinking agent is disclosed. The crosslinkable cellulosic fibrous product can be formed as a web or sheet that has structural integrity and sheet strength sufficient to permit the fibrous web to be rolled, transported, and used in rolled form in subsequent processes. The crosslinkable fibrous product can be converted into a crosslinked fibrous product by subjecting the product to conditions sufficient to effect intrafiber crosslinking. Alternatively, the web can be fiberized and the resulting individual crosslinkable fibers combined with other fibers and/or other materials to provide a fibrous web containing crosslinkable cellulosic fibers. Subjecting such a web to crosslinking conditions provides a fibrous web that includes, in addition to other fibers or materials, crosslinked cellulosic fibers.
Abstract: An aqueous binder composition containing a urea-formaldehyde resin modified with a water-soluble styrene-maleic anhydride copolymer is used in the preparation of fiber mats.

Abstract: Modified melamine-formaldehyde resins prepared by reacting melamine with formaldehyde at a F:M molar ratio in the range of about 1.55:1-2.5:1 under alkaline conditions, wherein the resin is prepared in the presence of about 1-10 wt % dicyandiamide and about 1-10 wt % sorbitol based on the total weight of resin solids. The resins are used to impregnate substrates in the preparation of decorative laminates. The laminates can be used to produce, for example, furniture, countertops or flooring.
