Abstract
Procedure for obtaining polyesters, characterized in that compounds showing at least two carboxyl groups and their anhydrides are reacted with synthesizing compounds of ester groups, such as cyclic acetals and/or ketals of formulas **(See formula)** where R and R'are the same or different and signify hydrogen, C1-C18-alkyl, C4-C14-cycloalkyl or C6-C14 -aryl or together they form a C4-C7-cycloalkylene residue, R''means an aliphatic residue n-valent with 1 to 18 carbon atoms, a cycloaliphatic residue with 4 to 14 carbon atoms or an aromatic residue with 6 to 14 carbon atoms and n represents 2 or 3 and X means H, C1-C18-alkyl or C2- C18-alkenyl.
