Abstract

Procedimiento para la producción de una dispersión de partículas polimericas estericamente estabilizadas en un medio acuoso, cuyas partículas polimericas son de un tamaño del orden de 0,1 a 10 micras, caracterizado porque comprende la polimerización iniciada por radicales libres, en un medio acuoso, de uno o más monómeros etilenicamente insaturados, a una temperatura que es al menos 10ºC más elevada que la temperatura de transición vitrea del polímero formado, en presencia, en el medio acuoso, y como estabilizante estérico, de un copolimero en bloque o de injerto que contiene en la molécula un componente polimérico de un tipo que es solvatable por el medio acuoso y un componente polimérico de otro tipo que no es solvatable por el medio acuoso y que es capaz de llegar a asociarse con las partículas polimericas formadas; siendo el medios acuosos una mezcla que comprende (a) al menos 30% en peso de agua y (b) no mas de 70% en peso de un segundo constituyentes que es miscible con agua, siendo tales la naturaleza y proporción del segundo constituyente que la mezcla, como un conjunto, es capaz de disolver el monómero o monómeros a polimerizar en un grado de al menos 35% en peso, pero no es un disolvente para el polímero formado, mantenimiento durante todo el proceso la concentración de monómero libre en la mezcla de polimerización a un nivel tal que ningún momento el momento libre forme un fase separada y siendo tal la cantidad total de monómero polimerización que la dispersión resultante contiene al menos 20% en peso de polímero.
