Abstract

En particular, los materiales de moldeo de polímero de estireno de gran impacto y estireno/acrilonitrilo se preparan en solucion en dos etapas mediante un proceso en el cual el copolímero de bloque de estireno/butadieno, cuyos extremos de cadena viviente si se requiere se acoplan y/o se terminan, se prepara mediante polimerizacion anionica en una primero zona de reaccion que, por lo menos en su ultima seccion, en la direccion de trabajo, consiste de un reactor que tiene un flujo de tapon, en particular un reactor de tubo, y el copolímero de bloque se alimenta directamente a una segunda zona de reaccion de la cual el homopolímero de estireno se propara mediante polimerizacion de radical libre o copolimerizacion.
