An independent claim is included for a process of preparing the polycondensate comprising mixing polyol, (non)aromatic monocarboxylic acids, heating the mixture at 100-130[deg]C, preferably 150-220[deg]C until complete consumption of the acids, optionally cooling the mixture at 90-150[deg]C, adding the polycarboxylic acid and/or the cyclic anhydride acids, and optionally a silicone with hydroxyl or carboxyl groups, and heating at =220[deg]C.
