Zusammenfassung:	A PROCESS FOR THE PRODUCTION OF HIGH MOLECULAR WEIGHT, OPTIONALLY BRANCHED POLYARYLENE SULFIDES A b s t r a c t The invention relates to a process for the production of high molecular weight, optionally branched polyarylene sulfides having a low content of organically bound halogen. The are prepared by reaction of alkali sulfides and/or alkali hydrogen sulfides with aromatic dihalogen compounds in a polar organic solvent. Le A 26 274
