A process for producing a hydrogenated and acidic functional- ized polymer from a polymer initially containing either ethylenic unsaturation or both aromatic and ethylenic unsaturation comprising the steps of: (a) incorporating one or more precursors of an acidic functional group into the starting polymer; (b) hydrogenating the product from step (a) so as to convert at least a portion of the ethylenic unsaturation initially contained in said polymer; (c) converting at least a portion of the precursors incorporated in the hydrogenated polymer from step (b) to the corresponding acidic functional group; and (d) recovering a product containing acidic functionality which is at least partially hydrogenated.
