Abstract

Copolymers of particularly low viscosity, which can be prepared by a polymerization in bulk, in which one component (A) is initially charged and, in the further course of the polymerization, at least two olefinically unsaturated copolymerizable monomers (B) are added, of which at least one contains at least one COOH group and at least one is sterically-hindered are usefully employed in coating compositions.
