Abstract
1.- Proceso para polimerizar monómero de vinil cloruro y monómeros adicionales opcionales utilizando uno o más iniciadores, con al menos parte de dichos iniciadores siendo dosificados a la mezcla de reacción polimerizante, caracterizado por que al menos un iniciador orgánico con una vida media desde 0,0001 horas hasta 0,050 horas a la temperatura de polimerización es dosificada a la mezcla de reacción polimerizante en dicha temperatura de polimerización.2.- Un proceso de acuerdo a la reivindicación 1 que comprende una etapa en donde al menos parte de la dosis de uno o más de los iniciadores es controlada de tal forma que la capacidad de enfriamiento deseada, el reactor se utiliza, preferiblemente aunque manteniendo la temperatura de la mezcla de polimerización constante.3.- Un proceso de acuerdo a la reivindicación 1 o 2 en donde al menos parte de el o los iniciadores se dosifican después de que al menos 40% p/p, preferiblemente al menos 60% p/p, de todo el monómero se ha polimerizado.
