| Abstract: | Phenyldiazomethane was found to be polymerized by the reaction with palladium‐based initiating systems. Homopolymerization of phenyldiazomethane afforded a polymer, whose main chain consists of phenylmethylene framework (–CHPh–) and azo groups (–N?N–). The incorporation of the azo group was suggested from the results of elemental analyses, and confirmed by Raman spectroscopy. Palladium‐mediated copolymerization of phenyldiazomethane with (E)‐1‐diazo‐3‐nonen‐2‐one or ethyl diazoacetate proceeded to give copolymers having phenylmethylene framework, azo group, and acylmethylene or ethoxycarbonylmethylene framework in the main chain, with a variety of their compositions. © 2006 Wiley Periodicals, Inc.
