Abstract

Proceso para la preparación de polvos de redispersión vinilaromático-polímero mixto redispersables en agua por medio de polimerización en emulsión iniciada por radicales libres de una mezcla de comonómeros que contiene a)uno o más comonómeros vinilaromáticos, b) uno o más comonómeros de 1,3-dieno (b1) o uno o más comonómeros (b2) del grupo de los alquilésterescon1 a 8 átomos C de ácido acrílico o ácido metacrílico, y c) 0,1 a 10 % en peso, referido al peso total de la mezcla de comonómeros, de uno o más comonómeros del grupo de los ácidos monoo dicarboxílicos etilénicamente insaturados o sus anhídridos, de las amidas de ácido carboxílico etilénicamente insaturadas, de los compuestos de ácido sulfónico etilénicamente insaturados, y de sus sales respectivas, y secado de la dispersión acuosa de copolímeros que puede obtenerse de este modo, en el cual se añaden ademása la dispersión acuosa de copolímeros antes de o durante la polimerización o antes del secado uno o más ácidos hidroxicarboxílicos o sus sales en una cantidad de 3 a 40 % en peso, referida a la proporción de copolímero.
