USES

PROPERTIES
Polyesters can be formed from the reaction of a diacid or acid anhydride and a diol with the elimination of water, or by ring-opening polymerization of cyclic (di-)esters. According to the composition of their main chain, polyesters are classified as aliphatic, semi-aromatic and aromatic (see table below). Aromatic reactants improve the hardness, rigidity, and heat resistance, whereas aliphatic acids and diols increase the flexibility, lower the melting or softening point and improve the processability.
