Abstract

Procedimiento para la obtención de un terpolímero modificado con caucho, de composición uniforme, que sigue siendo susceptible de que se le dé forma térmicamente tras haber sido expuesto a temperaturas de 190ºC durante 30 minutos, seguido por amasado en un mezclador Brabender a 240ºC durante dos minutos, que comprende polimerizar una mezcla monómera de 50 a 83 por ciento en peso de un monómero vinilaromático, de 15 a 30 por ciento en peso de un anhídrido de ácido dicarboxílico insaturado y de 2 a 20 por ciento en peso de un nitrilo insaturado, en presencia de 2 a 30 por ciento, basado en el peso de la composición, de un sustrato de caucho injertado con un polímero de superestrato y dispersado en un terpolímero de matriz, caracterizado por formar una solución de dicho monómero vinilaromático, dichos monómeros de nitrilo insaturado y dicho caucho, iniciar catalíticamente la polimerización de la mezcla por debajo de 120ºC, con adición tardía continua de dicho anhídrido de ácido dicarboxílico insaturado durante la polimerización.
