Abstract
1.- Proceso en donde dos o más iniciadores son usados para polimerizar una mezcla que contiene uno o mas monómeros de los cuales uno es monómero de cloruro de vinilo, en donde un sistema de iniciación convencional se agregó a la mezcla de polimerización en la primera parte de la reacción de polimerización y uno o más iniciadores adicionales se agregan a la mezcla de polimerización en la temperatura de reacción cuando la presión en el reactor de polimerización cae debido al agotamiento del monómero de cloruro de vinilo y dichos iniciadores adicionales tienen una vida media de menos de 1 hora en la temperatura de polimerización, con la condición que el polímero formado no está sujeto a calentamiento dieléctrico de radiofrecuencia en la presencia de un iniciador orgánico adicional.2.- Un proceso de acuerdo a la reivindicación 1 en donde el iniciador agregado después de iniciar la caída de la presión y/o durante la caída de la presión tiene una vida media de 0,0001 hora a 1 hora en la temperatura de polimerización.3.- Un proceso de acuerdo a la reivindicación 2 en donde el iniciador orgánico adicional agregado después y/o durante la caída de la presión tiene una vida media de 0,0001 hora a 0,05 hora en la temperatura de polimerización.4.- Un proceso de acuerdo a una cualquiera de las reivindicaciones 1-3 en donde al menos parte de los iniciadores se agrega intermitentemente y/o continuamente después empezar la caída de la presión y/o durante la caída de la presión.
