Abstract: A process for preparing aqueous dispersions of polymers containing oxazoline groups, by aqueous emulsion polymerization initiated by free radicals. The polymerization are carried out in two stages. In the first polymerization stage, an ?,?-monoethylenically unsaturated compound having at least one acid group, an monoethylenically unsaturated compound having at least one carboxylic acid amide group, a monoethylenically unsaturated compound having at least one carboxylic acid amide group are copolymerized. In the second polymerization stage, a monoethylenically unsaturated compound having at least one oxazoline group, a monoethylenically unsaturated compound having at least one carboxylic acid amide group and an ethylenically unsaturated compound are copolymerized with the final product from the first polymerization stage.

Abstract: Described are aqueous polymer dispersions for composite film lamination, comprising a dispersed polymer and a dissolved polymer, and also a multistage process for preparing them from ethylenically unsaturated, radically polymerizable monomers. In a first stage, a first polymer is prepared by radical emulsion polymerization. In a second stage, an aqueous polymer dispersion is prepared in the presence of the first polymer. The monomers of the first stage comprise monomers with acid groups. The dissolved polymer comprises monomers having oxazoline groups, and also water-soluble monomers. The aqueous polymer dispersions can be used as adhesive for producing composite films.
