Formation of acid anhydride of various polymeric carboxylic acids was examined. As the polymers were used alternative copolymers of maleic anhydride and nonionizable comonomers such as vinyl acetate, vinyl benzoate, vinyl pyrrolidone, methyl acrylate, methyl methacrylate and styrene, the hydrolysis product of the alternative copolymer of diethyl fumarate and styrene, atactic polymers of monocarboxylic acids such as acrylic acids, methacrylic acid, crotonic acid, vinyl acetic acid, p<I></I>-vinyl benzoic acid and atropic acid, and atactic polymers of dicarboxylic acids such as maleic anhydride, citraconic acid and itaconic acid. In general, acid anhydride rings of five members could be more easily formed than those of six members. With the exception of some polymers, the polymers which are considered to contain neighbored carboxyl groups with shorter spacial distances showed greater abilities for acid anhydride formation. Some discussions were given for these results.
