Abstract
An improved procedure for preparing linear polyesters, reacting a free dicarboxylic acid and a glycol of the HO (CH2) nOH series, where n is an integer from 2 to 10, with water separation, and subsequent condensation with glycol separation, characterized by carrying out the esterification in the presence of a catalytic amount of a catalyst chosen from the group consisting of organic titanium carboxylic acid salts, organic zirconium carboxylic acid salts, zirconium β-diketonates, titanium β-diketonates, oxides organic titanium and organic zirconium oxides.
