Abstract

PURPOSE: To produce a carboxyl group-containing polymer material in good reaction efficiencies, by esterifying a hydroxyl group-containing polymer with a cyclic acid anhydride in the presence of a swelling agent under an anhydrous condition.
CONSTITUTION: A substance, e.g., dimethyl sulfoxide, which is unreactive with a cyclic acid anhydride but acts upon a hydroxyl group-containing polymer as a swelling agent (nonsolvent for said polymer, e.g., benzene, can also be used in combination). Namely, 100pts.wt. hydroxyl group containing polymer, e.g., polyvinyl alcohol polymer, saponification degree ≥ about 90mol% or a variety of celluloses and about 20W200pts.wt. cyclic acid anhydride, e.g., maleic anhydride, are reacted in the presence of said swelling agent under an anhydrous condition. Here, the carboxyl groups of the polymer prepared by the above method may be converted into carboxylate groups by neutralization with a monovalent-metal compound or an ammonium compound.
