Rhodium-Catalyzed Copolymerization of Norbornadienes and Norbornenes with Carbon Monoxide

“…Copolymerization of olefins and carbon monoxide is a topic of current academic and industrial interest. During the 1950s to 1970s, the copolymerization of olefins with carbon monoxide initiated by free radicals or induced by γ-rays under high pressure and high temperature was reported . In recent years, use of transition-metal catalysts has been receiving much attention because the copolymerization catalyzed by transition-metal complexes occurs under a lower pressure and at a temperature as low as 25 °C, and the resultant polymers have a strictly alternating structure and significantly higher molecular weight .…”
