摘要： A reaction system for forming a viscoelastic polyurethane foam includes an isocyanate component and an isocyanate-reactive component that includes at least a polyol component, an additive component, and a preformed aqueous polymer dispersant. The mixture includes 50.0 wt % to 99.8 wt % of the polyol component, 0.1 wt % to 49.9 wt % of the additive component, and 0.1 wt % to 6.0 wt % of the preformed aqueous polymer dispersant. The aqueous polymer dispersant has a pH from 6.0 to 12.0 and includes from 5 wt % to 60 wt % of a polymeric component and from 40 wt % to 95 wt % of a fluid medium. The polymeric component includes at least one base polymer derived from 20 wt % to 100 wt % of at least one hydrophilic acid monomer having at least one carbonyl group, phosphate group, phosphonate group, or sulfonyl group, and optionally derived from at least one hydrophobic terminally unsaturated hydrocarbon monomer.

摘要： The present invention relates to a composition comprising an aqueous dispersion of polymer particles; b) anion exchange resin particles; and c) an aminosilane. The composition achieves a more desirable balance of stain blocking and stain removal properties in pigmented coating formulations over compositions that contain the latex and the aminosilane but no anion exchange resin, or the latex and the ion exchange resin but no aminosilane.
