Abstract

Procedimiento para preparar una composición de polímero resinoso con elevada resistencia a los impactos, caracterizado por las siguientes operaciones: a) se obtiene por lo menos un copolímero en bloque radial resinoso de por lo menos un compuesto aromático monovinil sustituido y por lo menos un dieno conjugado, B representa un bloque de dieno conjugado polimerizado Y representa un residuo del agente de acoplamiento polifuncional, y n representa el número de grupos funcionales del agente de acoplamiento que han entrado en la reacción de acoplamiento y es un número entero igual por lo menos a 3, b) se obtiene por lo menos un copolímero en bloque lineal resinoso de por lo menos un compuesto aromático monovinil sustituido y por lo menos un dieno conjugado c) se mezclan dichos copolímeros en bloques radial y lineal en una mezcla que tiene un índice de heterogenidad de dichos bloques compuestos aromáticos monovinil sustituidos incluido en la gama de 2,5 a 4.
