| titleOfInvention | Process for producing halogenated aromatic polyesters |
| abstract | Halogenated aromatic polyesters having the recurring structural formula ##STR1## wherein X is chlorine or bromine and Y is hydrogen, chlorine or bromine, with the provision that when X is chlorine, Y is hydrogen or chlorine and when X is bromine, Y is hydrogen or bromine, R and R' may be the same or different and represent lower alkyl groups, hydrogen, or together constitute a cyclic hydrocarbon group, and n is an integer which is at least about 10, are prepared by n (a) reacting in solution in the presence of an excess amount of a tertiary amine n (1) a bisphenol having the structural formula ##STR2## wherein X, Y, R and R' have the same meanings as given above; with (2) an aromatic acid halide selected from the group consisting of terephthaloyl halide, isophthaloyl halide, and mixtures thereof to form a reaction mixture comprising solvent, tertiary amine hydrochloride, unreacted tertiary amine, and the halogenated aromatic polyester, n (b) adding to the reaction mixture an amount of gaseous, substantially anhydrous, hydrogen chloride sufficient to substantially completely neutralize the unreacted tertiary amine, and n (c) recovering the halogenated aromatic polyester. |
