Abstract: Polymers useful for imparting flame resistance to fibers and textiles are provided herein. The polymers are water-soluble, phosphine oxide-containing polymers that may be reaction products of hydroxymethyl phosphonium salts or hydroxymethyl phosphines with linking monomers, wherein at least 20% of the phosphorous atoms of the polymer are present as phosphine oxides. Formulations including the polymers and methods of using the polymers to impart flame resistance to fibers and textiles are also disclosed.

Abstract: Described herein are textile- and/or foam-based multilayer cushioning assemblies that include a thermally-conductive layer, which imparts beneficial thermal management properties without a significant adverse effect on flexibility and/or cushioning properties, so the textile- and/or foam-based multilayer compositions remain suitable for use in bedding, furniture, clothing, and other applications where they will contact a user and where user comfort is important.

Abstract: An emulsion includes at least one polymeric surfactant, water and at least one organophosphorous compound. The emulsion may include from about 1% to about 40% of the polymeric surfactant and from about 40% to about 80% of the organophosphorous compound. The emulsion may further include at least one salt or additional surfactant. The at least one polymeric surfactant may include silicone-based surfactants, polyoxypropylene-based surfactants, graft copolymers of polysaccharides, and combinations thereof. The at least one polymeric surfactant may account for about 25% to about 100% by weight of the surfactant content in the emulsion and the at least one secondary surfactant, if present, may account for up to about 75% by weight of the surfactant content in the emulsion. The emulsion may have an average dispersed phase drop size of less than about 5 micron, or less than about 1 micron, after 6 months.
