Abstract: The present invention relates to aqueous acrylic polymer latexes, which are suitable as binders in coating compositions for providing flexible roofing. The present invention also relates to coating compositions containing such binders, which are suitable for providing flexible roofing. The aqueous acrylic polymer latexes have a glass transition temperature Tg of at most from −10° C., in particular at most −20° C., or, in case of a multi-stage polymer latex a weight average glass transition temperature Tg of at most from −10° C., where the polymer of the acrylic polymer latex has a carbon polymer backbone formed by polymerized ethylenically unsaturated monomers M comprising acrylic monomers, and where the carbon polymer backbone bears functional groups of the formula (I) attached to carbon atoms of the polymer backbone *—C(═O)—O-[A-NH]nH (I) where the asterisk indicates the atom attached to a carbon atom of the polymer backbone, n is an integer, the number average of n in all functional groups of the formula (I) being >1, in particular at least 1.1 or at least 1.2 or at least 1.3, and A is selected from the group consisting of 1,2-ethandiyl or 1,2-propandiyl, where the functional groups of the formula (I) contribute to the total weight of the polymer in the acrylic polymer latex by 0.1 to 10% by weight.

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.

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 α,β-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 and 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 further 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 monomers of the further stage comprise monomers having oxazoline groups. The polymerization of the first stage takes place at a low pH of less than 5. The acid groups of the first polymer are neutralized before the polymerization of the further stage. The aqueous polymer dispersions can be used as adhesives for producing composite films.
