Abstract

La presente invención se refiere a el procedimiento para polimerizar o copolimerizar monómeros de acrilato para formar polímeros de acrilato, solubles en agua, de bajo peso molecular, que usan un agente de transferencia de cadena de ácido hipofosforoso, junto con iniciadores de polimerización, agua y activadores de polimerización opcionales, en una mezcla polimerizadora acuosa, agitada y calentada, que contiene los monómeros, la mejora que comprende alimentar concurrentemente el agente de transferencia de cadena del ácido hipofosforoso y el neutralizador alcalino a la mezcla polimerizadora de monómeros, de manera que el neutralizador alcalino este presente durante al menos la mayoría, si no toda, la polimerización, en una cantidad suficiente para neutralizar al menos el 20 por ciento de los grupos ácido de los monómeros carboxílicos presentes.
