Abstract
Abstract The polymer films of the invention contain reactive groups and are obtained from phenols of the formula ##STR1## in which R denotes an acyl group with 1 to 7 carbon atoms, a hydroxy, carboxy, alkoxycarbonyl, amino, alkylamino or phenylamino group, and n is an integer, which may be 0 in the case where R is an acyl group. The films are prepared by electrolytic polymerisation on metallic surfaces and can be used to graft various materials reacting therewith, as intermediate layers.
