Dihalophenyl-bis-(hydroxyarylethers)
Abstract
Abstract with 2 mols of a dialkali metal phenolate of the formula (IV) MeO - Ar - OMe IN WHICH Me denotes an alkali metal, in a polar organic solvent at temperatures between about 60* C and about 180* C, preferably between about 90* C and about 160* C, and acidifying the reaction mixture and their utility for rendering unsaturated polyester resins and epoxide resins barely inflammable. where Z denotes a bivalent aliphatic, cycloaliphatic or araliphatic radical with 1 - 8 carbon atoms or -O-, -S-, -SO-, SO2- or -CO- and the aromatic nuclei may carry 1 - 4 alkyl or alkoxy groups with 1 - 4 carbon atoms or halogen atoms, prepared by reacting 1 mol of a tetrahalobenzene of the formula (III) in which R1 and R2 denote hydrogen or identical or different alkyl or alkoxy radicals with 1 - 4 carbon atoms; Hal is chlorine, fluorine or bromine; and Ar is phenylene, naphthylene, diphenylene or a polynuclear aromatic radical of the formula (II) Compounds of the formula (I)
