Abstract: A chemical composition for use in the papermaking process to produce a paper having enhanced characteristics of brightness, opaqueness, and sizing is provided. The process using the composition to make the paper and the paper made therefrom are also provided by the present invention. The composition is made by combining an amphoteric softener such as a salt of an amphoteric stearic acid derivative, a cationic softener base, such as the mono- and distearamides of aminoethylethanolamine, an acid, such as acetic acid, a surfactant, such as POE (15) tallow amine, carbamide, and water. In another embodiment, a saccharide may be employed instead of the amphoteric stearic acid derivative, surfactant and carbamide. To speed the production of the composition, a viscosity controlling agent, such as sodium chloride or sodium acetate, may be added thereto.

Abstract: A paper coating composition is prepared containing a pigment, a binder and as an insolubilizer for the binder a zirconium chelate containing an alpha-hydroxy carboxylic acid ligand.

Abstract: An adhesive composition is prepared containing an aqueous copolymer emulsion which contains a first polymer network which is intertwined on a molecular scale with a second polymer network.

Abstract: A paper coating composition is prepared containing a polymer emulsion which comprises a first polymer network which is intertwined on a molecular scale with a second polymer network.

Abstract: A cationic polyvinyl alcohol binder additive is prepared suitable for addition in the wet-end of a paper making process by reacting a blocked glyoxal resin, a cationic water-soluble aldehyde reactive polymer and a polyvinyl alcohol polymer.

Abstract: Monomers such as hydrophobic olefinically unsaturated monomers have been grafted onto maltodextrins and other low molecular weight starch hydrolyzates to prepare stable fluid emulsions of coatable viscosity and reduced graininess. Polymer films of high tensile strength which are useful in a variety of applications, including high temperature applications may be formed by casting and drying these emulsions.

Abstract: A water-dispersible, self-crosslinking non-formaldehyde latex is prepared by reacting a starch-polymer graft with a glyoxal compound at temperatures of at least 70.degree. C. to produce a stable emulsion with low viscosity and which upon drying and curing provides a film having good tensile, elongation, water resistance and anti-wicking properties.

Abstract: Modified starch dispersions are prepared by gelatinizing various starches and starch blends and reacting the starch in the presence of a glyoxal compound to produce an aqueous starch dispersion having a storage-stable and coatable viscosity. The starch dispersions provides a film which displays good tensile strength and elongation properties.

Abstract: A binder for non-woven fibers or fabrics is prepared comprising a starch-polymer graft, starch and a starch crosslinking agent. An acrylamide copolymer may optionally be included. The binder is useful for non-woven fibers such as a polyester fiber mat, and particularly single ply, bitumin roofing materials.

Abstract: Paper coating compositions contain at least one pigment, at least one binder, and as an insolubilizer for the binder, the product of reacting glyoxal with a polyhydroxyl substituted ester, then with a polyol.

Abstract: A coating binder additive is prepared comprising a blocked glyoxal resin mixed with a vinyl or acrylic water soluble polymer which is reactive with free glyoxal.

Abstract: N-acyl substituted cyclic ureas are prepared which are useful as blocked isocyanates in one-component polyurethane systems.
