Abstract
Un método de polimerizar una masa polimerizable que contiene estireno y que consiste en mezclar con dicha masa una combinación catalizadora compuesta de 007 a 011 por ciento de perbenzoato de butilo terciario y 011 a 007 por ciento de peróxido de benzoilobasándose dichos porcentajes en el peso del estireno contenido en dicha masacalentar la masa que contiene catalizador a una temperatura de como 100º C. en un lapso de como 08 a 12 horas y mantener esa temperatura durante como 18 a 22 horascalentar luego dicha masa que contiene catalizador a una temperatura de como 115ºC. en un periodo de 04 a 06 horas y mantener esa temperatura durante como 18 a 22 horasy calentar después dicha masa que contiene catalizador a una temperatura de como 135ºC. en un lapso de como 04 a 08 horas y mantener esa temperatura por espacio de hasta como una horacon lo que se permite que la concentración de radicales libres de dicha masa que contiene catalizador aumente tan sólo en una cantidad muy ligera durante las etapas sucesivas de calentamiento y se efectúa una polimerización virtualmente completa durante la etapa final de calentamiento.
