ABSTRACT:
Unsaturated esters can be prepared from dicarboxylic acids and dibromoneopentyl glycol with improved resin color in a shorter reaction time with minimal corrosion of metallic reaction vessels and with a net energy saving by the process using an aryl sulfonic acid as the esterification catalyst and following completion of the reaction neutralizing the acid catalyst.
