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.
