摘要

A process for producing a polymer of excellent weatherability, which comprises reacting a polymer having a thioether bond, with a peroxide to oxidize the sulphur atom in the bond to convert it into a sulphone. In one process the sulphone- containing polymer is reacted with an unsaturated compound to form a macromolecule which may be copolymerised with another monomer. In another process the thioether-containing polymer may be reacted with an unsaturated compound to form a macromolecule which is copolymerised and then oxidised.
