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.

Abstract: Described are aqueous polymer dispersions and a method for producing them. The polymer dispersions comprise polymer particles having an average particle diameter of greater than 200 nm, monomodal particle size distribution, and uniform glass transition temperature, and are prepared by radical emulsion polymerization of a monomer mixture comprising ethylenically unsaturated, radically polymerizable monomers, using a polymer seed, less than 0.8 part by weight of emulsifier, and without protective colloids. The monomer mixture consists of a) at least 60 wt % of at least one monomer selected from the group consisting of C1 to C20 alkyl acrylates, C1 to C20 alkyl methacrylates, vinyl esters of carboxylic acids containing up to 20 carbons, vinylaromatics having up to 20 carbons, ethylenically ensaturated nitriles, vinyl halides, vinyl ethers of alcohols containing 1 to 10 carbons, aliphatic hydrocarbons having 2 to 8 carbons and one or two double bonds, and mixtures of these monomers, b) at least 0.1 wt % of at least one monomer having at least one acid group; c) optionally further monomers, the acid groups of the monomers b) being wholly or partly neutralized during the emulsion polymerization. The aqueous polymer dispersions can be used as adhesives, more particularly for the production of composite films.
