AQUEOUS DISPERSIONS OF PLASTICS HAVING A REDUCED FORMALDEHYDE CONTENT ABSTRACT OF THE DISCLOSURE The invention relates to aqueous dispersions of plastics having a solids content of 30 to 70% by weight and a reduced formaldehyde content, based on polymers of one or more monomers from the group comprising acrylic acid esters, methacrylic acid esters, vinyl esters, olefins, vinyl halides, vinylaromatics and ethylenically unsaturated carboxylic acids and amides thereof, and a content of 0 to 10% by weight, based on the total weight of the polymer, of N-alkylamides and/or N-alkoxyalkyl- amides of ethylenically unsaturated carboxylic acids, wherein the dispersion contains 0.05 to 10% by weight, based on the polymer, of one or more peroxy compounds from the group comprising hydrogen peroxide, organic peroxides, perborates, percarbonates, persulfates and perphosphates. The dispersions of plastics modified according to the invention are suitable for use as binders, coating agents, impregnating agents and adhesives in all fields in which a low formaldehyde content or a reduced release of formaldehyde during processing is required.
