Abstract
Procedimiento para la obtencion de una dispersion acuosa de polimerizado, en el que una dispersion acuosa de un polimerizado, que contiene incorporado en forma químicamente ligada, como mínimo, un monomero que presenta al menos un grupo etilénicamente insaturado, es generada en forma en si conocida, de tal modo, que el contenido total de la dispersion acuosa de polimerizado en monomeros libres, a saber, no ligados químicamente, y que presentan al menos un enlace doble etilénicamente insaturado, con respecto a la dispersion acuosa de polimerizado, ascienda de > 0 hasta <- 1% en peso, y este contenido residual de monomeros es luego reducido por la accion de un sistema de iniciacion redox de radicales libres, que comprende al menos un oxidante y al menos un reductor, donde el sistema de iniciacion redox comprende como un reductor un mercaptano que contiene junto con el grupo mercaptano al menos otros grupo funcional.
