Abstract

Process for the preparation of linear aromatic polyesters characterized by polycondensing aromatic dicarboxylic acids, or their polyester-forming derivatives, with two bifunctional hydroxylic compounds, one of which is unbranched and the other corresponds to the formula: ** (see formula) ** Wherein r represents a methyl group, methoxyphenyl or a heterocyclic nucleus and a represents a methylene or phenylene group or other unbranched and bivalent group of at most 5 links which may contain, in addition to the carbon atoms, heteroatoms such as oxygen and sulfur.
