Alternating copolymerization of carbon monoxide and olefins by single-site metal catalysis

摘要

The alternating copolymerization of carbon monoxide and olefins is a reaction that transition metal complexes, generally containing palladium, catalyze in different phase variation system. The polyketone products are not only low cost thermal plastics that can be made but also polymeric materials featured by unique chemical and physical properties. These properties can be finely tuned by an appropriate choice of the catalyst and olefinic comonomer. After introducing the topic, the specific metal catalysts for each type of olefinic substrate are described together with the reaction mechanisms involved.
