Abstract

En la presente se proveen métodos para procesar caucho natural, también denominado látex, sin el uso de amoníaco. Los métodos provistos en la presente pueden comprender uno o más de los siguientes pasos: (a) un paso de recolección de en donde el látex líquido se recolecta de una planta y, preferentemente, se filtra para eliminar las impurezas del medioambiente; (b) un paso de estabilización en donde una composición de látex líquido se refrigera y/o se pone en contacto con un agente de estabilización; (c) un paso de preservación en donde la composición de látex líquido se pone en contacto con un agente de preservación; (d) un paso de ajuste del pH en donde la composición de látex líquido se pone en contacto con un agente para el ajuste del pH; (e) un paso en donde la composición de látex líquido se almacena durante un período de tiempo; y (f) un paso de coagulación en donde la composición de látex líquido se pone en contacto con un agente de coagulación y de ese modo formar una composición de látex sólido. También se proporcionan en la presente composiciones de látex líquido estabilizadas y preservadas que tienen una vida útil prolongada y dichas composiciones de caucho sólido tienen propiedades física y químicas ventajosas.
