Synthesis of polyketones

New Routes to Polymer Building Blocks

Polyketones with low CO content and molecular weight in the oligomer range were obtained with unprecedented efficiency by using a new protocol for the palladium-catalysed copolymerisation of CO and ethylene. Key physicochemical properties such as resistance to degradation and melting point were traced back to the microstructure of the polyketones. With properties tailored to the application, non-alternating polyketones emerge as interesting materials for demanding applications, where alternating polyketones are currently being used. Furthermore, the keto groups constitute interesting anchoring sites for introducing functionalities.
