Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO DE FABRICACION DE UNA COMPOSICION QUE COMPRENDE UN POLIMERO VINILAROMATICO UN CAUCHO, CARACTERIZADO POR QUE LA ETAPA DE POLIMERIZACION SE REALIZA EN PRESENCIA DE UN RADICAL LIBRE ESTABLE. LA PRESENCIA DE UN RADICAL LIBRE ESTABLE EN EL MEDIO DE POLIMERIZACION PERMITE AUMENTAR EL INDICE DE FLUIDEZ E INFLUIR EN LA DIMENSION DE LOS NODULOS DE CAUCHO EN LA COMPOSICION FINAL AUMENTANDO GENERALMENTE LA FRACCION DE VOLUMEN DE FASE DE CAUCHO Y AMPLIANDO LA DISTRIBUCION DE LA DIMENSION DE ESTOS NODULOS. ESTO SE TRADUCE EN UNA MEJORA A LA VEZ DEL INDICE DE FLUIDEZ Y DE LA RESISTENCIA AL CHOQUE DE LA COMPOSICION FINAL, LO QUE HACE DE ESTA UNA COMPOSICION IDEAL PARA EL MOLDEADO POR INYECCION.
