    Abstract: Procedimiento para la mejora de la estabilidad de dispersiones polímeras acuosas, que se obtienen por polimerización en emulsión acuosa por medio de radicales de monómeros M etilénicamente insaturados, que comprenden al menos un 50 % en peso, referido a la totalidad del peso de los monómeros M, de uno o varios monómeros M1, que se escogen entre monómeros vinilaromáticos, los ésteres alquílicos con 1 a 12 átomos de carbono y los ésteres cicloalquílicos con 5 a 8 átomos de carbono de ácidos mono- y dicarboxílicos etilénicamente insaturados con 3 a 8 átomos de carbono, butadieno, cloruro de vinilo y de vinilideno y olefinas con 2 a 6 átomos de carbono, frente a la influencia térmica y/o mecánica, caracterizado porque se agrega al menos una sal de un éster bisalquílico con 4 a 18 átomos de carbono de un ácido dicarboxílico sulfonado con 4 a 8 átomos de carbono (= sal S) a la dispersión polímera acuosa.
