Abstract Novel photo-crosslinkable polymers are obtained by reacting, and polycondensing, bis-(hydroxyalkyl) succinylo- succinates 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 use- ful as solvent-resistant membranes for reverse osmosis.
