Abstract of the Disclosure Novel substantially linear, or at least partially cross-linked, nitrogen-containing polymers having an aryleneimine or arylenether unit in the main chain with an amino group or a group derived from it being bonded as a pendant group to a nuclear carbon atom of the arylene group of the above unit. According to the number and type of the pendant groups, the polymers can have various useful properties such as thermal stability, hydrophilicity, oxidative reducibility, photosensitivity, color formability or the ability to form coordination bonds. Furthermore, the polymers have good solubility in aprotic polar organic solvents. Permselective membranes having good performance can be prepared from solutions of the polymers in these solvents.
