Abstract

Se proporciona un método para recuperar un monómero de nitrilo a,ß-insaturado etilénicamente sin reaccionar contenido en un látex de un caucho de nitrilo obtenido por polimerización en emulsión de una mezcla monomérica que comprende un monómero de nitrilo a,ß-insaturado etilénicamente y un monómero que contiene grupo carboxilo. El método comprende los pasos de: ajustar un pH del látex del caucho de nitrilo que contiene grupo carboxilo a 6.5 o más; descomprimir el látex del caucho de nitrilo que contiene grupo carboxilo que tiene el pH ajustado a 6.5 o más bajo una condición de calentamiento; y recuperar un componente evaporado por la descompresión bajo la condición de calentamiento.
