  • METHOD FOR PRODUCING POLYESTEROLS HAVING A REDUCED REACTIVITY
    Publication number: 20090227759
    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.
