Abstract

En la presente invención se describe un método para preparar copolímeros de bloques ahusados. polimodales, en un proceso de polimerización, al cargar en forma secuencial: (a) un iniciador y monómeros monovinilaromáticos en la presencia de un agente de aleatoriedad; (b) un iniciador y monómeros monovinilaromáticos; (c) una mezcla de monómeros de dieno conjugado y de monovinilaromáticos; (d) una mezcla de monómeros de dieno conjugado y de monovinilaromáticos; (e) un iniciador y monómeros monovinilaromáticos; (f) una mezcla de monómeros de dieno conjugado, y de monovinilaromáticos; (g) una mezcla de monómeros de dieno conjugado, y de monovilaromáticos; (h) monómeros de dieno conjugado; y (i) un agente de acoplamiento. Los copolímeros son útiles particularmente para aplicaciones en envases, que requieren buena resistencia al agrietamiento por fatiga ambiental.
