Abstract: Copolymers of particularly low viscosity which can be prepared by bulk polymerisation in which component (A) is introduced at the beginning of the polymerisation and at least two olefinically unsaturated, copolymerisable monomers (B), of which at least one contains at least one COOH group and at least one is sterically hindered, are added during the further course of the polymerisation.

These dispersions are suitable as water-dilutable binders for stoving (baking) varnishes or stoving solid-colour top coats.

Also claimed is the above process for the prodn. of (I). Also claimed are 1-component paints with (I) as binder and formaldehyde/amino-resin reaction prods. (opt. etherated with 1 - 8 C aliphatic alcohol) as hardeners, and 2-component paints with (I) as binder and polyisocyanates or urethane-forming polyisocyanate derivs. as hardeners.

Also claimed are: (i) a process for the prodn. of (I) by bulk polymerisation in the presence of aliphatic azo cpds., diacyl peroxide, alkyl per-esters, alkyl hydroperoxide, dialkyl peroxide or peroxy-di-carbonate as radical initiators; and (ii) a process for the prodn. of water-dilutable polyacrylate dispersions by: (A) dissolution of (I) in a water-dilutable organic solvent, followed by: (B) partial or complete neutralisation, and (C) dilution by adding water or stirring the soln. into water.
