Abstract

Procedimiento para la preparación de mezclas pulverulentas, listas para su elaboración, a base de polímeros de cloruro de vinilo con un contenido de cloruro de vinilo monómero ampliamente reducido en comparación con el polímero de cloruro de vinilo pulverulento se mezcla juntamente con sustancias auxiliares de elaboración en varios mezcladores sucesivos provistos de herramienta agitadora, calentándose la mezcla pulverulenta en el primer mezclador hasta una temperatura final de 70 a 160ºC y enfriándose en el último mezclador a temperatura ambiente, caracterizado por el hecho de que después de alcanzar la temperatura final la mezcla pulverulenta se sigue mezclando a una temperatura de 70 a 160ºC y sólo entonces se enfría.
