Verfahren zur Herstellung von aromatischen Polymeren |
摘要 |
Prepn. of O- and/or S- contg. aromatic polymers having benzene groups in their chain by reacting (I) a bis-(halophenylsulphonyl)-benzene cpd., (II) opt. another dihalobenzenoid cpd., and (III) an alkali metal hydroxide, with separation of the formed alkali metal halide, the reaction being carried out in a stable polar liquid forming an ionising solvent for alkali metal phenoxides. (I) pref. has formula X-C6H4-SO2-Ar-SO2-C6H4-X X = halogen; Ar= a difunctional aromatic group derived from benzene, diphenyl, a terphenyl, or an aromatic hydrocarbon with a condensed ring and not more than 3 aromatic rings. (II) is pref. a bis (4-halophenyl)-sulphone. |
