    Abstract: Copolymers prepared by emulsion or solution copolymerization, initiated by free radicals, of unsaturated copolymerizable monomers, the copolymers being built up from (a) 1-45% by weight of ethylenically unsaturated carboxylic acids, (b) 0.5-30% by weight of a surface-active crotonic acid ester, (c) 30-85% by weight of methacrylic acid esters or acrylic acid esters of aliphatic (C1-C18)-alcohols, (d) 0-40% by weight of other ethylenically unsaturated comonomers, (e) 0-3% by weight of polyethylenically unsaturated compounds and (f) 0-5% by weight of molecular weight regulators, and, if appropriate, the free acid groups of the copolymers subsequently having been partly or completely neutralized by addition of bases and converted into water-soluble or colloidally water-dispersible copolymer salts. In addition, processes for the preparation of the copolymers by solution or emulsion copolymerization and, if appropriate, subsequent conversion thereof into the copolymer salts, and the use of the products as viscosity-increasing and rheology-modifying substances in aqueous systems, in particular aqueous dispersions, preferably for thickening emulsion paints, emulsion gloss lacquers, textile printing pastes and paper printing pastes, and furthermore as sizing agents in the textile industry.

    Abstract: 20731-1103 Aqueous polymer dispersions based on A) 1 to 99% by weight of a carboxy-functional polymer which additionally contains epoxy groups, B) 1 to 99% by weight of a polymer obtained from at least one .alpha.,.beta.-olefinically unsaturated monomer, the polymer B) having been prepared in the presence of polymer A), C) 0 to 20% by weight of anionic or non-ionic emulsifiers or a mixture thereof or of protective colloids, the percentage by weight relating to the solids content of components A) to C), and if appropriate further conventional additives. The invention also discloses a process for the preparation of such polymer dispersions, which are particularly useful as a binder component in metallic basecoats or metal-free (uni) basecoats and electrocoatings. Compared with similar dispersions known from the prior art, the dispersions allow the formulation of rheologically controllable metallic basecoat paints which, after application, show good intercoat adhesion combined with excellent stability on storage in water.

    Abstract: Aqueous polymer dispersions based on (A) 1 to 99% by weight of a carboxy-functional polymer which additionally contains epoxy groups, (B) 1 to 99% by weight of a polymer obtained from at least one alpha , beta -olefinically unsaturated monomer, the polymer (B) having been prepared in the presence of polymer (A), (C) 0 to 20% by weight of anionic or non-ionic emulsifiers or a mixture of the two or protective colloids, the quantity data relating to the solids content of components (A) to (C), and if appropriate further conventional additives, the sum of all the components always being 100%. The invention also relates to a process for the preparation of such polymer dispersions, which are particularly suitable as a binder component in metallic basecoats or metal-free, (uni) basecoats and electrocoatings.
