Abstract
Copolymers consisting of divalent diphenyl ether and biphenyl moieties connected by sulphone groups, in which the ratio of diphenyl ether to biphenyl moieties is in the range of 4: 6 to 29: 71 may be prepared by copolymerizing monomers containing diphenyl ether and biphenyl moieties, either or both of the monomers containing sulphonylhalide groups at a temperature of 25 DEG C. to 300 DEG C. in the presence of a condensation catalyst. Suitable monomers are p,p-di(chlorosulphonyl)diphenyl ether, monochlorosulphonyl diphenyl ether, monochlorosulphonyl biphenyl, p,p-dichlorosulphonyl biphenyl, biphenyl, bis(biphenyl) sulphone and diphenyl ether. The polymerization reaction is preferably carried out in the presence of an inert solvent such as chlorinated aliphatic and aromatic hydrocarbons, aliphatic and aromatic sulphones or aliphatic and aromatic nitro compounds. Suitable catalysts are Friedel-Crafts catalysts such as ferric chloride, aluminium chloride, zinc chloride, indium trichloride and antimony pentachloride or anhydrous hydrofluoric acid or trifluoromethane sulphonic acid. The copolymers may be dissolved in a solvent, e.g. N,N-dimethylformamide and used to form coatings and films.ALSO:Copper wire may be coated with a solvent solution of a copolymer consisting of divalent diphenyl ether and biphenyl moieties connected by sulphone groups, in which the ratio of diphenyl ether to biphenyl moieties is in the range of 4:6 to 29:71. An example describes the coating onto copper wire of such a polymer dissolved in N,N-dimethylformamide as solvent.
