Abstract

Procedimiento de preparación de copolímeros injertado, caracterizado por las etapas sucesivas siguientes: se somete un polímero a la acción del ozono, se pone este polímero así ozonizado en presencia de un monómero polimerizable por un mecanismo radicalar, después se descomponen los ozonidos formados sobre el polímero, iniciando así la polimerización de los monómeros sobre el polímero inicial.
