A polymer for use in an optical device comprising a first, optionally substituted, repeat unit of formula and a second, optionally substituted, repeat unit of formula wherein each Ar and Ar' is the same or different and comprises an optionally substituted aryl or heteroaryl group and optionally a third, optionally substituted, repeat unit in a molar ratio of no greater than 5%, the third repeat unit having a formula &#x2014;Ar&#x2014;N(Ar)&#x2014;Ar&#x2014; and having a single nitrogen atom in its backbone.

Polymers their preparation and uses

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.
