Abstract

Una mejora en un procedimiento continuo para hacer emulsiones de fase interna alta que son típicamente polimerizadas para proveer materiales de espuma poliméricos microporosos, de celda abierta, capaces de absorber fluidos acuosos, especialmente fluidos acuosos del cuerpo, tales como orina. La mejora implica la recirculacion de una porcion (aproximadamente 50% o menos) de la emulsion retirada de la zona de mezclado dinámico de éste procedimiento continuo. Esto incrementa la uniformidad de la emulsion finalmente obtenida de este procedimiento continuo en términos de tener gotas de agua homogéneamente dispersadas en la fase de aceite. Esto también mejora la estabilidad de la HIPE y expande la escala de temperatura para vaciar y curar esta HIPE durante la polimerizacion de emulsion subsecuente.
