Abstract

La presente invención se refiere a un procedimiento para la producción de artículos de hule que comprende los pasos de: a) inmersión de un molde configurado en una mezcla de látex de hule acuosa para formar una película continua de hule sobre dicho molde; b) secado y curado de dicha película de hule sobre dicho molde; c) remoción de la película de hule seca y curada de dicho molde, caracterizado además porque dicha mezcla de látex de hule acuosa es una mezcla de látex de hule natural y un látex de copolímero de estireno-butadieno, en la que el látex de copolímero de estireno-butadieno se emplea en proporciones dentro de la escala de alrededor de 1 a aproximadamente 25 partes por cien partes, en peso, de látex de hule natural, sobre una base sólida y en la que el copolímero de estireno-butadieno contiene más de 50 por ciento en peso de estireno polimerizado, siendo el resto butadieno polimerizado.
