Procedure

The procedure of Example 1 was repeated except that there was employed 3.0 parts of 4,4'-diphenyletherdithiol, 4.68 parts of 3-chlorophthalic anhydride, 2.85 parts of triethylamine and 38 parts of anhydrous DMF. The mixture was stirred at 50° C. for 3 hours to give a product which after acetic acid/acetic anhydride treatment consisted of a 93% yield of product. Recrystallization of this material from toluene/acetic anhydride gave a product in 87% yield, mp 224°-228° C. Based on the method of preparation the product was a thioetherdianhydride of the formula ##STR15##
