Abstract

La presente invencion es un procedimiento de polimerizacion en volumen de radical libre para la preparacion de polímeros de peso molecular alto a partir de monomeros aromáticos de vinilo, caracterizado porque la polimerizacion es conducida en presencia de un ácido vinílico conteniendo un átomo ya sea de azufre o de fosforo dentro del grupo funcional de ácido.
