Abstract

Procedimiento para la obtención de polímeros segmentadoscaracterizados porque un polímero elevado termoplástico y normalmente sólido se mastica en una atmósfera que contiene oxígenoauna temperatura inferior a 170ºC; por cuyo medio se forman grupos peróxido en el polímeroy luego se somete a condiciones que den lugar a la descomposición de los grupos peróxidosen presencia de un compuesto monómero que contenga uno o más enlaces dobles olefínicosy susceptible de polimerización sometido a la influencia de radicales libres; esta última etapase realiza en ausencia de una concentración de oxígeno queen otro casoinhibiría la polimerización del compuesto monómero citado.
