Abstract

La presente invencion se refiere a un polímero aromático de monovinilideno modificado con caucho que posee una distribucion de tamano de partícula bimodal,que comprende: a) partículas de caucho de un caucho de baja viscosidad de estrella o ramificadocon un tamano de partícula promedio en volumen de 0,1 a 1,5micrones, y morfología de nucleo/coraza o celular o una mezcla de las mismas, y b) partículas de caucho de un caucho de baja viscosidad de estrella oramificado, caucho de dieno lineal, o caucho de copolímero de bloque con un tamano de partícula promedio en volumen de 1,5 a 10 micrones y una morfologíacelular con la condicion que cuando el tamano de partícula promedio en volumen de la partículas de a) es mayor de 1 micron, el tamano de partícula promedio envolumen de las partículas de b) es de por lo menos 2 micrones, en donde las partículas de a) son de entre 50 y 99% en peso del contenido total de caucho dedieno. También se revelan composiciones que incluyen dichos polímeros y artículos elaborados con dicha composicion.
