Abstract
Un procedimiento para deshidratar un látex acuoso de caucho injertado, caracterizado por las etapas de: A) mezclar un látex de caucho de dieno injertado con un monómero alquenilnitrilo y optativamente un monómero alquenilaromático, consistiendo dicho caucho de dieno en partículas de caucho injertadas con monómero alquenilaromático y alquenilnitrilo, siendo dichas partículas de caucho emulsionadas en dicho látex acuoso por un agente tensioactivo aniónico, B) dispersar un agente tensioactivo catiónico en dicho látex en cantidad suficiente para desemulsionar dichas partículas de caucho, C) extraer dichas partículas de caucho de dieno injertadas en dichos monómeros como una fase oleosa líquida, formando dicho látex acuoso una fase acuosa separada, y D) separar dicha fase acuosa de dicha fase oleosa líquida.
