    Abstract: Polyesterols having reduced reactivity are prepared by catalytic polycondensation of dicarboxylic acids/dicarboxylic acid derivatives and H-functional substances using tin catalysts by a process wherein the polyesterols are brought into contact with oxygen after the end of the esterification reaction.The polyesterols themselves obtained by this process are used for the preparation of PU.
