Abstract

A process for producing a polyvinyl acetal resin through reaction of polyvinyl alcohol with a carbonyl compound, characterized in that the content of alkali metal salts of polyvinyl alcohol is 300 ppm or less in terms of alkali metal, and that the reaction is performed at 40° to 200°C in the presence of carbonate catalyst. Thus, there is provided an efficient process for producing a polyvinyl acetal resin of high quality strikingly reduced in the residue of impurities, such as metal salts and acids.
