ABSTRACT:
A universal method to make photosensitive polymers from poly(vinyl alcohol) and poly(vinyl pyridine) is disclosed which generally does not require final purification. These polymers comprise a heterocyclic, light-sensitive pendant group including a moiety having the formula: ##STR1## wherein Z.sup.1 denotes the atoms necessary to form a substituted or unsubstituted aromatic heterocyclic ring; Z.sup.2 denotes the atoms necessary to form a substituted or unsubstituted aromatic or aromatic heterocyclic ring; R is hydrogen or a substituted or unsubstituted alkyl group; M is a divalent organic moiety; Y is a residue from a grafting group that is capable of grafting the pendant group onto a polymeric backbone.
