ABSTRACT:
Polymeric compounds comprise groups of the formula ##STR1## attached to carbon atoms of a polymer containing hydroxyl and optionally epoxide groups wherein X is ##STR2## The compounds are produced by reacting a starting polymer, which contains hydroxy groups and optionally epoxide groups with a reagent containing a cyclic anhydride group and a further functional group capable of reacting with the hydroxyl (and/or epoxide) groups preferentially to the anhydride group. The compounds are useful as bakeable support resins for radiation sensitive compounds in the production of printing plates.
