Abstract Bis(1,5‐cyclooctadiene)dirhodium(I)dichloride and bis(norbornadiene)‐dirhodium(I)dichloride are effective catalysts for polymerization of 1,5‐hexadiyne. The structure of the polymer obtained and its behaviour towards oxidation and oxidizing agents has been elucidated by means of infrared and ultraviolet spectroscopy. It is proposed that polymerization proceeds with formation of a polymer having a five‐membered ring in each of its monomeric units. The polymer is highly conjugated and can be obtained directly during polymerization as film, which has a metallic lustre, is insoluble in common solvents, and shows good resistance to oxidation in air, if sufficiently thick.
