Abstract

Process for obtaining high molecular weight polyesters, characterized in that ethylene glycol is reacted with an ester-forming compound of terephthalic acid and an azelaic acid-forming compound, constituting the terephthalic acid units of 90 to 99.0 mol % of the sum of the units of both acidic compounds and the azelaic acid units of 10 to 1.0 mole% of the units of both acidic compounds present, forming glycol esters of the acids and subsequently condensing the glycol esters separating the glycol.
