METHOD FOR PRODUCING POLYESTER RESIN HAVING CYCLIC ACETAL SKELETON

摘要

Provided is a method for producing a polyester resin that is formed from dicarboxylic acid structural units and diol structural units and that comprises at least structural units having a cyclic acetal skeleton as the diol structural units, the method for producing a polyester resin comprising a step for reacting a diol (A) having a cyclic acetal skeleton, a dicarboxylic acid bis-alkyl ester (B), and a diol (C) that does not have a cyclic acetal skeleton in the presence of a basic compound (D).
