    Abstract: Solid organic inert flatting agents are prepared by reacting urea or phenol and formaldehyde in a basic aqueous medium to provide a prepolymer solution, then blending the prepolymer in the presence of a protective colloid-forming material, subsequently acidifying the basic prepolymer solution so that particles are formed and precipitated in the presence of a colloid-forming material, as spheroidal beads, and finally collecting and, if desired, drying the urea or phenol formaldehyde particulate beads. These beads have a high flatting efficiency and may be incorporated in resinous vehicles to provide compositions that produce low glass coatings of desirable properties.

    Abstract: Two-package polymeric compositions which form cured products having excellent stain and solvent resistance and having improved potlife comprise a polyepoxide and an addition interpolymer containing pendent salt groups formed by reacting carboxyl groups with a hindered amine and pendent amine groups formed by reacting carboxyl groups with an alkylenimine. The addition interpolymer when mixed with the polyepoxide reacts to form a cured, hard, stain and solvent resistant material. The stability of the mixed compositions, i.e., its potlife, is lengthened by utilizing a sterically-hindered tertiary amine to form the salt groups of the interpolymer.Stability of the addition interpolymer prior to mixing is improved by utilizing therein monomers which provide aminolysis-resistant groups in the interpolymer.

    Abstract: A pigment dispersion which includes a pigment, an aqueous carrier and a pigment dispersant. The pigment dispersant is prepared by controlled radical polymerization initiated in the presence of a monomeric initiator having at least two radically transferable groups. The pigment dispersant has at least one of the following polymer chain structures: &phgr;-[(G)p—(E)s—T]z and &phgr;-[(E)3—(G)p—T]z where G is a hydrophobic residue of at least one radically polymerizable ethylenically unsaturated monomer; E is a hydrophilic residue of at least one radically polymerizable ethylenically unsaturated monomer; &phgr; is a residue of or derived from the initiator, and is free of the radically transferable group; T is or is derived from the radically transferable group of the initiator; z is 2 to 10; p and s are at least one and are selected such that the pigment dispersant has a number average molecular weight of at least 500.
