Abstract
Polycondensation reactions of diesters having phenolic hydroxyl groups with diamines were carried out in order to investigate the enhancement effect of the phenolic hydroxyl group on the polycondensation. Aromatic hydroxyl diesters derived from salicylic acid or hydroquinone had a higher reactivity toward diamines than the reactivity of ordinary diesters. However, their reactivity was inferior to that of aliphatic hydroxyl diesters such as tartarate. The enhancement effect of the phenolic hydroxyl group was presumed to be due to an interaction of the hydroxyl group with the approaching amine.
