Abstract

Procedimiento para la obtención de copolimerizados de estireno antichoque, modificados con caucho, caracterizados porque se polimeriza el estireno en presencia del caucho en, como mínimo dos etapas, prepolimerizándose en la primera etapa el estireno que contiene el caucho disuelto a una temperatura de entre 50 y 150ºC, en caso dado en presencia de diluyentes indiferentes y/o inciadores que forman radicales libres, bajo separación de la fase dispersa de componente blando que se forma durante la polimerización mediante cizallamiento de la mezcla de polimerización y continuándose la polimerización en una o varias etapas bajo cizallamiento redicudo o sin cizallamiento, en solución, suspensión acuosa o en ausencia de disolventes hasta alcanzar la conversación deseada, en el cual durante la prepolimerización.
