Abstract: Water-dilutable dispersions of acrylate copolymers having a hydroxyl number of from 40 to 200 mg of KOH/g and an acid number of from 15 to 50 mg of KOH/g, obtained by free-radical copolymerization of a) from 5 to 40 parts by weight of at least one glycidyl ester of an aliphatic, saturated monocarboxylic acid which is branched in the alpha -position, b) from 0 to 30 parts by weight of at least one diester of an alpha , beta -olefinically unsaturated dicarboxylic acid, c) from 0 to 70 parts by weight of at least one vinyl aromatic hydrocarbon, where the molar amount of component c) is always greater than or equal to the molar amount of component b), d) from 0 to 60 parts by weight of an alkyl ester of an alpha , beta -olefinically unsaturated carboxylic acid, e) from 2 to 40 parts by weight of at least one alpha , beta -olefinically unsaturated carboxylic acid, where the molar amount of component e) is always greater than the molar amount of component a), f) from 5 to 40 parts by weight of at least one hydroxyalkyl ester of an alpha , beta -olefinically unsaturated carboxylic acid, where the polymerisation is carried out in the presence or absence of solvents, optionally with addition of a water-dilutable solvent, neutralisation and dilution with water. These dispersions are suitable as water-dilutable binders for stoving (baking) varnishes or stoving solid-colour top coats.

Abstract: Copolymers (I) of olefinic monomer(s) comprise an isomeric mixt. of esters of isobornyl alcohol with an alpha , beta -unsatd. acid. The isomeric alcohol mixt. contains: (a) not more than 92% isoborneol, (b) at least 3.5% iso-fenchyl alcohol, and (c) at least 1% pseudo-bornyl alcohol. 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.
