Abstract

Se describe el proceso para preparar soluciones acuosas de polímeros del ácido acrílico polimerizando el ácido acrílico en modo de alimentación con un iniciador de radicales en presencia de hipofosfito, en agua como disolvente, como sigue: (i) introducir inicialmente agua y, como una opción, uno o más comonómeros con insaturación etilénica, (ii) adicionar en forma continua ácido acrílico en su forma ácida, no neutralizada, como una opci'n, uno o más comonómeros con insaturación etilénica, solución acuosa del iniciador de radicales y solución acuosa de hipofosfito, (iii) después de terminar la alimentación de ácido acrílico, adicionar una base a la solución acuosa no excediendo el contenido de comonómero 30% en peso, con base en el contenido total del monómero, adicionando la solución acuosa de hipofosfito durante un tiempo de alimentación total compuesto de tres lapsos de tiempo de alimentación sucesivos ?tI, ?tII y ?tIII, siendo la velocidad promedio de alimentación del segundo lapso del tiempo de alimentación ?tII mayor que las velocidades promedio de alimentación del primer y segundo lapsos de los tiempos de alimentación ?tI y ?tIII.
