Method for producing polyesterpolyols of polyvalent alcohols |
| abstract |
The invention relates to a method for producing polyesterpolyols of polyvalent alcohols by the mono- or polyesterification of at least one carboxylic acid containing at least two acid groups and/or at least one derivative of a dicarboxylic acid with polyvalent alcohols, optionally with the addition of a catalyst and by separating the reaction water. Said method is characterised in that the polyvalent alcohol used has a formaldehyde acetal content of less than 500 ppm. |
