The use of polyamine- and/or polyalkanolamine-based carboxylic acid derivatives as additives in aqueous polymer dispersions for production of porous polymer coatings, preferably for production of porous polyurethane coatings, is described.
PROCESSES, POLYURETHANE COMPOSITIONS AND POLYURETHANE PRODUCTS HAVING AMINE-BASED THERMOLATENT CATALYST
A process for preparing a polyurethane product, and polyurethane compositions and products of the process. The process includes preparing a catalyst composition comprising at least one tertiary amine salt, wherein the at least one tertiary amine salt is a contact product of at least one carboxylic acid and at least one tertiary amine, wherein the at least one tertiary amine is selected from the group consisting of N-hydroxyethylpiperidine and tris(dimethylaminomethyl)phenol; and reacting at least one isocyanate, at least one polyol and the catalyst composition to form a polyurethane product.

IN-SITU GELATINOUS TRIBLOCK COPOLYMER ELASTOMERS IN LATEX FOAMS
Combinations of gelatinous elastomer and polyurethane foam may be made by introducing a plasticized A-B-A triblock copolymer resin and/or an A-B diblock copolymer resin into a mixture of polyurethane foam forming components including a polyol and an isocyanate. The plasticized copolymer resin is polymerized to form the gelatinous elastomer in-situ while simultaneously polymerizing the polyol and the isocyanate to form polyurethane foam. The polyurethane reaction is exothermmic and can generate sufficient temperature to melt the styrene-portion of the A-B-A triblock copolymer resin thereby extending the crosslinking and in some cases integrating the A-B-A triblock copolymer within the polyurethane polymer matrix. The combination has a marbled appearance. The gel component has higher heat capacity than polyurethane foam and thus has good thermal conductivity and acts as a heat sink. Another advantage of in situ gel-foam is that the gel component provides higher support factors compared to the base foam alone.

COSMETIC COMPOSITION CARRIER COMPRISING LATEX FOAM
The present invention provides a cosmetic composition carrier comprising a latex foam having a density of 0.05-0.2 g/cm.sup.3 and a cosmetic product comprising same. The cosmetic composition carrier according to the present invention has excellent filling, holding, and discharge capabilities with respect to a liquid cosmetic, has excellent antibacterial activity, can be filled with, hold, and discharge liquid cosmetic compositions in a wide range of low to high viscosities, thus allows excellent color expression and uniform application without caking when a liquid cosmetic composition held in the cosmetic composition carrier is applied to the skin, and allows the application of the liquid cosmetic composition to a portable container.
FOAM FORMULATION AND METHOD OF PREPARING SOLID POROUS MATERIALS WITH SAME
A foam formulation for preparing polymer-grafted nanoparticles stabilized foam, including nanoparticles, monomers of a polymer to be grafted on the nanoparticle surface, polymerization initiator, surfactant and water. The polymer-grafted nanoparticles may act together with the surfactant to form single-layer assembling at the boundary of bubbles, which in turn stabilizes the foam. The generated foam shows much better stability in long-term storage, high-temperature drying process and alkaline environments than conventional wet foams. A method of preparing solid porous materials with the foam is also provided.
Low density attached polyurethane foams made using a combination of frothing and blowing methods
Textiles backed with a polyurethane cushion are produced by applying a layer of frothed polyurethane-forming mixture to a surface of the textile. The mixture contains both water and a physical blowing agent. The layer expands due to the action of the water and the physical blowing agent and cures to form an attached cushion having a density of 176 g/L or less.
