ABSTRACT:
A semipermeable, porous, asymmetric membrane containing a polyetheramide which contains at least one or more dicarboxylic acid derivatives and aromatic diamines having a portion. The membrane is suitable for applications where contamination by glycerol or other platicizers or pore fillers must not be tolerated, may be dried without using a pore filler such as glycerol, does not collapse upon drying, and are sufficiently hydrophobic to be wetted again after complete drying.
