Abstract: A method for producing a polymer dispersion, by polymerizing a mixture X containing a urethane resin (A3), a monomer (b5) having two or more radically polymerizable groups, and a radically polymerizable monomer (b6) other than the monomer (b5), to obtain a dispersion containing a polymer P; and adding a pre-emulsion prepared by emulsifying and dispersing a radically polymerizable monomer mixture Y dropwise to the dispersion containing the polymer P and conducting polymerization, to obtain a dispersion containing a polymer Z, where a content of the urethane resin (A3) in the mixture X at the time of starting the reaction in the step (1) is from 25 to 95% by mass with respect to a total mass of the mixture X.

Abstract: Water-based stains are based on an oil-in-water emulsion having a binder that includes, consists of, or consists essentially of drying oil combined with a non-aqueous polymer dispersion. The compositions can be tinted using traditional water-based pigment dispersions, yet the overall hydrophobicity results in minimal interaction with the polar cellulosic structure of wood.

Abstract: Hydroxypolyamides, hydroxypolyamide products, and post-hydroxypolyamides are disclosed as gel forming agents. Hydroxypolyamides and post-hydroxypolyamides are prepared from known methods. Hydroxypolyamide products are produced from a modified polymerization procedure which utilizes strong base for deprotonation of ammonium salts from the esterification of stoichiometrically equivalent polyacid:polyamine salts. The hydroxypolyamide products are capable of gel formation at lower concentrations than hydroxypolyamides and post-hydroxypolyamides from the known methods of preparation, and are therefore superior gel forming agents.
