Bromine-containing aromatic copolyether sulfones

Bromine-containing copolyether sulfones on the basis of 2,2-di(4-hydroxyphenyl)propane, 4,4'-dichlorodiphenylsulfone and decabromine diphenyloxide were synthesized. The polymers obtained are amorphous substances soluble in common organic solvents and are suitable for the manufacture of saong clear films capable of thermal cross-lining
