ABSTRACT:
Novel photo-crosslinkable polymers are obtained by reacting, and polycondensing, bis-(hydroxyalkyl) succinylosuccinates or bis-(hydroxycycloalkyl) succinylosuccinates with maleic anhydride, maleinimid or N-methylmaleinimid in a molar ratio of 1:1 to 1:2. The novel polymers are useful as photoresists, and the films consisting of the crosslinked polymers are useful as solvent-resistant membranes for reverse osmosis.
