    Abstract: Pigment dispersants for use in coating compositions wherein the dispersant is the polymerization product of (i) an alkyl methacrylate having from 3 to 8 carbon atoms in the alkyl group, (ii) a hardening monomer selected from the group consisting of a styrene, methyl methacrylate, ethyl methacrylate and mixtures thereof, (iii) an ethylenically unsaturated carboxylic acid selected from the group consisting of acrylic acid, methacrylic acids, itaconic acid, crotonic acid, maleic acid, fumaric acid and mixtures thereof or a monomer having a double bond alpha-beta to a carbonyl group and which provides carboxyl functionality when reacted with water, alcohol, amine or anhydride, (iv) a monomer having a double bond alpha-beta to a carbonyl group and at least one hydroxyl group or a monomer which provides such groups when further reacted with an acid or an epoxide, and (v) a compound providing an amine or amine salt functional moiety. The dispersants are useful for dispersing pigments in coating compositions containing a wide variety of film-forming resins.

    Abstract: Amine group-containing addition interpolymers having improved stability under conditions of storage and use are prepared by interpolymerizing at least one polymerizable ethylenically unsaturated carboxylic acid monomer and at least one polymerizable ethylenically unsaturated aminolysis-resistant organic monomer to form an addition interpolymer containing carboxyl groups pendent to the polymer chain and aminolysis-resistant organic groups pendent to the polymer chain, following which a portion of the pendent carboxyl groups of the addition interpolymer are reacted with an alkylenimine to form pendent amine groups and a portion of the pendent carboxyl groups of the addition interpolymer are neutralized with a basic compound to form pendent anionic salt groups. The addition interpolymer is preferably reducible with organic solvents, water or a mixture thereof, and can be utilized as pigment grinding vehicles or they can be formulated with conventional additives to form useful coating compositions. A preferred use for these interpolymers is in combination with a polyepoxide to provide two-package cocurable polymeric compositions for coatings and other uses.
