Abstract
Abstract A process for preparing a light-sensitive high molecular weight polymer compound, which comprises reacting an Beta -unsaturated carboxylic acid with an aliphatic or aromatic diepoxide to form the corresponding diol compound and reacting a diisocyanate compound with said diol compound and a process for preparing the light-sensitive high molecular weight polymer compounds, and to the novel polymer compounds produced.
