Abstract

Procedimiento para la obtención de una dispersión acuosa de polimerizado, en el que una dispersión acuosa de un polimerizado, que contiene incorporadoen forma químicamente ligada, como mínimo, un monómero que presenta al menos un grupo etilénicamente insaturado, es generada en forma en si conocida, de talmodo, que el contenido total de la dispersión acuosa de polimerizado en monómeros libres, a saber, no ligados químicamente, y que presentan al menosun enlace doble etilénicamente insaturado, con respecto a la dispersión acuosa de polimerizado, ascienda de > 0 hasta l 1% en peso, y este contenido residualde monómeros es luego reducido por la acción de un sistema de iniciación redox de radicales libres, que comprende al menos un oxidante y al menos un reductor,donde el sistema de iniciación de redox comprende como reductor un mercaptano que contiene junto con el grupo mercaptano al menos otro grupo funcional.Process for obtaining an aqueous dispersion of polymer, in which an aqueous dispersion of a polymer, which contains, in a chemically bound form, at least one monomer having at least one ethylenically unsaturated group, is generated in a manner known per se, in such a way that the total content of the aqueous polymer dispersion in free monomers, that is, not chemically bonded, and that have at least one ethylenically unsaturated double bond, with respect to the aqueous polymer dispersion, is from> 0 to l 1 % by weight, and this residual content of monomers is then reduced by the action of a free radical redox initiation system, which comprises at least one oxidant and at least one reducer, where the redox initiation system comprises as a reductant a mercaptan that together with the mercaptan group it contains at least one other functional group.
