Abstract

Proceso para la modificacion de un polímero o copolímero con la estructura general (1) para una o más de las unidades repetitivas donde n es un entero, m es un entero dentro del rango entre 0 y 6, y R se selecciona entre hidrogeno, alquilo C1-20 sustituido o no sustituido, cicloalquilo C3-20, arilo C6-20, aniquilo C7-20, y alcarilo C7-20, donde dichos grupos pueden incluir unidades alquilo lineal o ramificado; donde los uno o más sustituyentes opcionales se seleccionan entre el grupo que consiste en los grupos hidroxi, alcoxi, alqu(en)ilo lineal o ramificado, ariloxi, halogeno, ácido carboxílico, éster, carboxi, nitrilo, y amido, donde dicho proceso incluye poner en contacto el polímero o copolímero con un peroxido orgánico cíclico en las condiciones necesarias para que se descomponga por lo menos parte de dicho peroxido. Este proceso da corno resultado un (co)polímero con un alta grado de ramificacion pero libre de formacion de gel.
