Abstract: The invention relates to a method for reducing the amount of residual monomers in aqueous polymer dispersions means of chemical post-treatment. Post-treatment in the aqueous polymer dispersion is carried out by adding a redox system which contains a) 0.005-5 wt. % of an oxidation agent which contains an organic peroxide. and b) 0.005-5 wt. % of a reduction agent which contains sulfinic acids or salts thereof. Additionally the redox system can, optionally, contain catalytic amounts of a polyvalent metallic ion which can be treated in several valent stages. Post-treatment can be carried out at a temperature ranging from 20-100.degree. C. and at a PH-value ranging from 2-9. The invention also relates to the use of the inventive post-treated polymer dispersion for producing adhesives, coatings, powders, constructive chemical products or for refining textiles or paper.

Abstract: The present invention relates to aqueous plastic material dispersions based on vinyl ester copolymers, having a solids content of up to 80% by weight and a minimum film formation temperature below 20° C., which is substantially stabilized by ionic components, the vinyl ester copolymers containing at least one homo- or copolymer A and at least one homo- or copolymer B, methods for producing the same and the use thereof.

Abstract: The invention relates to aqueous coating agents containing binding agents and at least one aqueous plastic dispersion, based on one homopolymer and/or copolymer that is/are derived from ?,? unsaturated compounds (M). Said coating agents also contain at least one protective colloid containing hydroxyl groups and comprising ethylenically unsaturated groups and optionally additional feed material that is conventionally used for producing coating agents. According to the invention, the protective colloid contains ethylenically unsaturated groups in a quantity that is expressed as the molar degree of substitution MS of unsaturated groups, Runsaturated, ranging between 0.001 and 1.0. The invention also relates to a method for producing said coating agents and to their use for producing thixotropic coating agents by the addition of thixotroping agents, in particular metal chelates.
