Abstract
A process for preparing high molecular weight polymers or copolymers by Suzuki coupling. The catalyst used in the process comprises a source of palladium and a source of a phosphine characterized in that at least one substituent on the phosphine is an ortho substituted aryl group. The process is suitable for the preparation of polymers for use in electronic and optoelectronic applications.
