Halogen-containing, high-molecular, soluble, thermoplastic polyaryl polyethers
Abstract
Abstract The invention relates to new halogen-containing, high-molecular, soluble, thermoplastic polyaryl polyethers of the formula (I) in which R1 and R2 denote hydrogen or identical or different alkyl or alkoxy radicals with one to four carbon atoms; Hal is fluorine, chlorine or bromine; Ar is an unsubstituted or substituted phenylene, naphthylene, diphenylene or polynuclear bivalent aromatic radical of the formula (II) where R denotes a bivalent aliphatic, cycloaliphatic or araliphatic radical with one to eight carbon atoms or -O-, -S-, SO-, -SO2-or -CO-, X denotes a halogen atom or the radical -O -Ar -OH, Y denotes a hydrogen atom or the radical AND N DENOTES AN INTEGER FROM ABOUT 3 TO ABOUT 200. These new polyethers are produced by reacting molar amounts of a tetrahalobenzene or of several tetrahalobenzenes of the formula (III) and of a bisphenolate or of several bisphenolates of the formula (IV) Me -O -Ar -O -Me IN WHICH Me denotes an alkali metal, in a polar organic solvent at temperatures between about 80* C. and about 180* C.
