Abstract

Procedimiento para preparar una estructura polimérica microporosa tridimensional, relativamente homogénea e isotrópica, caracterizada porque comprende calentar una mezcla de un polímero termoplástico sintético elegido de entre el grupo formado por los polímeros de oxidación y sus mezclas, y un líquido compatible a una temperatura y durante un tiempo suficiente para formar una solución homogénea, dejar que dicha solución tome una forma deseada, enfriar dicha solución en dicha forma deseada a una velocidad y a una temperatura suficientes para iniciar la separación de fase líquido-líquido, sin equilibrio y termodinámica, continuar la refrigeración hasta formar un sólido y retirar del sólido resultante al menos una porción sustancial del líquido para formar la estructura de polímero microporoso.Procedure for preparing a three-dimensional, relatively homogeneous and isotropic microporous polymeric structure, characterized in that it comprises heating a mixture of a synthetic thermoplastic polymer chosen from the group formed by oxidation polymers and their mixtures, and a compatible liquid at a temperature and for a sufficient time to form a homogeneous solution, allow said solution to assume a desired shape, cool said solution in said desired shape at a rate and temperature sufficient to initiate thermodynamic, nonequilibrium, liquid-liquid phase separation, continue cooling until forming a solid and removing from the resulting solid at least a substantial portion of the liquid to form the microporous polymer structure.
