Polymers consisting of (a) vinyl compounds having a 2,2'-bipyridyl side group, (b) vinyl compounds having a radiation-sensitive side group and, if appropriate, (c) olefines which differ from (a) and (b), and their complexes with metal compounds, with the exception of alkali metal and alkaline earth metal compounds. They are suitable for coating substrates and for the preparation of photographic relief images. Complexes with cobalt salts are effective catalysts for the polymerization of acetylene.
