Abstract

La presente invencion se refiere al caucho de nitrilo que puede sintetizarse mediante la copolimerizacion de acrilonitrilo y 1.3 butadieno en un emulsion acuosa. Desde luego, después que estos monomeros se han polimerizado es necesario recuperar el polímero de la emulsion acuosa. La presente invencion describe un método mejorado para recuperar caucho de nitrilo a partir de una emulsion que contiene caucho de nitrilo, este método comprende los pasos de: (1) añadir un antioxidante a la emulsion que contiene caucho de nitrilo para producir un caucho de nitrilo estabilizado, (2) añadir una sal y un ácido a la emulsion de caucho de nitrilo estabilizada para producir una suspension de caucho de nitrilo coagulada, en donde la suspension de caucho de nitrilo coagulada contiene suero y grumos de caucho de nitrilo, (3) separar los grumos de caucho de nitrilo del suero de la suspension de caucho de nitrilo coagulado (4) mezclar los grumos de caucho de nitrilo en agua de lavado para producir una nueva suspension de caucho de nitrilo (5) ajustar el pH de la nueva suspension de caucho de nitrilo para que se encuentre dentro del rango desde cerca de 5 a cerca de 8, y (6) separar los grumos de caucho de nitrilo del agua de lavado de la nueva suspension de caucho de nitrilo. El caucho de nitrilo que se recupera de las emulsiones utilizando esta técnica por lo comun presenta mejores características de estabilidad y vulcanizado.
