Abstract
Perfeccionamientos introducidos en el objeto de la patente principal nº 442.452 por: Procedimiento para preparar mezclas pulverulentas listas para su transformación, a base de polimerizados de cloruro de vinilo, con un contenido de cloruro de vinilo monómero ampliamente reducido en comparación con el polimerizado de cloruro de vinilo empleado, procedimiento en el que el polimerizado de cloruro de vinilo, eventualmente junto con aditivos tales como estabilizadores lubricantes, plastificantes, cargas, pigmentos y agentes modificantes, se renueve intensamente por vía mecánica y se calienta al mismo tiempo, calentándose el material de la mezcla hasta una temperatura final de al menos 70ºC, y agregándose agua antes de ser alcanzada la temperatura final.
