Method for producing polyesterols having a reduced reactivity

A method for the production of polyesterols with reduced reactivity (I) by polycondensation of dicarboxylic acids or their derivatives with H-functional substances in presence of tin catalysts, involves bringing (I) into contact with oxygen after the end of the esterification reaction.

Zusammenfassung:	A method for the production of polyesterols with reduced reactivity (I) by polycondensation of dicarboxylic acids or their derivatives with H-functional substances in presence of tin catalysts, involves bringing (I) into contact with oxygen after the end of the esterification reaction. An independent claim is also included for polyesterols obtained by this method.
