ABSTRACT:
Semipermeable composite membranes which comprise an interpenetrating polymer network of the reaction product of a polyether and an isocyanate with a heterocyclic nitrogen-containing compound composited on a porous backing support material may be used in separation systems such as reverse osmosis, ultrafiltration, gas separation, dialysis, etc. The membranes of the present invention will permit the separation process to be efficient in an effective manner.
