Abstract

La presente invención se refiere a mejoras en membranas semipermeables resistentes al cloro, preparadas al vaciar una solución acuosa de una poliamina aromática que contenga un compuesto polihídrico sobre un material poroso de soporte; caracterizadas por eliminar el exceso de solución; poner en contacto el material de soporte poroso revestido con una solución disolvente orgánico de un haluro de ácido policarboxílico aromático para formar un producto de reacción de condensación de polimerización interfacial en la superficie del material de soporte poroso; curar el compuesto resultante en condiciones de cura para formar la membrana semipermeable resistente al cloro.The present invention relates to improvements in chlorine-resistant semi-permeable membranes prepared by pouring an aqueous solution of an aromatic polyamine containing a polyhydric compound onto a porous support material; characterized by removing excess solution; contacting the coated porous support material with an organic solvent solution of an aromatic polycarboxylic acid halide to form an interfacial polymerization condensation reaction product on the surface of the porous support material; Cure the resulting compound under cure conditions to form the chlorine resistant semipermeable membrane.
