Abstract

La presente invención se refiere a un metodo para preparar un copolímero mediante copolimerización de bloque en secuencia que consiste de polimerizar bajo condiciones de polimerización por solución or lo menos un mónomero de monovinilareno y por lo menos un monómero de dieno conjugado en una relación de aproximadamente 55 por ciento a 95 por ciento en peso de monovinilareno y de 45 por ciento a 5 por ciento en peso de dieno conjugado mediante un procedimiento de polimerización de carga en secuencia en donde por lo menos se emplean dos cargas cada una de dieno conjugado, de monovinilareno y de un iniciador de metal monoalcalino; por lo menos una carga de cada uno de monovinilareno y del dieno conjugado sigue la última carga del iniciador de metal monoalcalino; por lo menos una carga de dieno conjugado precede la última carga del iniciador de metal monoalcalino; cada carga monomerica se polimeriza hasta casi completarse antes de la adición de cualquier carga subsecuente; el número de carga de cada uno de dieno conjugado, monovinilareno y el iniciador de metal monoalcalino no es en exceso de 3 y el total de las cargas es de 8 o de 9; y luego acoplarse con un agente de acoplamiento polifuncional produciendo de esta manera un copolímero resinoso polimodal, resistente al agrietamiento, de poco colorido.
