Abstract
Procedimiento para la obtención de un látex de caucho libre de emulsionante, de 1 a 6 partes en peso de ácido (met)acrílico, y 94 a 99 partes en peso de una mezcla de 10 a 90 partes en peso de uno o más dienos conjugados acíclicos, conteniendo de 4 a 9 átomos de carbono, y 10 a 90 partes en peso de uno o más monómeros de arilvinilo, conteniendo de 8 a 12 átomos de carbono, y/o (met)acrilonitrilo, ascendiendo la cantidad del (met)acrilonitrilo como máximo a 50 partes en peso, caracterizado porque a) se prepara una emulsión acuosa agregando como mínimo parte del ácido (met)acrílico, parte del dieno y ulteriores monómeros al agua, b)la reacción de polimerización se inicia mediante la adición de una solución acuosa de peroxodisulfato, c) la polimerización se realiza en una primera etapa a un valor pH de 3,5 a 7 y a una temperatura superior a 70ºC hasta que hayan polimerizado como mínimo un 50% de los monómeros, y, en la última etapa, hasta que hayan polimerizado de un 85 a un 100% de los monómeros.
