A method for formulating an aqueous dispersion of a polymer includes dissolving a polymer such as an acrylic polyol in a solvent to form a polymer solution. A surfactant is added to the polymer solution, and water is then added with mixing sufficient to dispersed the polymer in the water. The resulting aqueous dispersion can be mixed with a water dispersible polyisocyanate to produce coating materials which can be cured to form tough films and coatings.

Aqueous dispersions of polymers

An aqueous dispersion containing a polyamide and non-polyamide polymer is prepared by dissolving the polyamide in an organic solvent with a surfactant to form a polyamide solution. Water is then added to the polyamide solution to form an aqueous dispersion. The non-polyamide polymer can be added before or after the addition of water. The polyamide/non-polyamide dispersion can be used to produce an ink with better adhesion to plastic substrates and reduced blocking problems.

Aqueous polyamide dispersion composition

A process is provided for preparing a dispersion of a polyamide in water, said process comprising:

Aqueous dispersions of polyamides

A water retention aid/thickener composition containing: (a) from about 40 to about 75% by weight of a C.sub.1 -C.sub.8 alkyl acrylate; (b) from about 60 to about 25% by weight of methacrylic acid; and (c) from about 0.1 to about 5% by weight of an alkoxylated acrylate or methacrylate monomer containing at least three vinyl moieties, all weights being based on the weight of the composition.
