Abstract

Procedimiento para la polimerización de monómero de cloruro de vinilo o de una mezcla de monómeros compuesta principalmente de cloruro de vinilo, en un medio de polimerización acuoso en presencia de un iniciador de polimerización y soluble en agua, caracterizado por las mejoras consistentes en que el medio de polimerización acuoso contiene un agente suspensor soluble en agua, porque el iniciador de polimerización insoluble en agua es sólido a temperatura ambiente y porque se añade el iniciador de polimerización a la mezcla de polimerización como una dispersión acuosa conteniendo al iniciador de polimerización teniendo un tamaño de partícula que no exceda de 50 um, mientras que la mezcla de polimerización se mantiene a una temperatura en el alcance desde la temperatura ambiente hasta una temperatura en el alcance desde la temperatura ambiente hasta una temperatura en que el periodo de vida media del iniciador de polimerización es de por lo menos 120 minutos.
