Process for producing (cyclo)aliphatic polycarbonate polyols having low reactivity |
| abstract |
The present invention relates to a process for producing (cyclo)aliphatic polycarbonate polyols comprising the steps ofn a) reaction of at least one (cyclo)aliphatic polyol and at least one alkyl carbonate in the presence of at least one basic catalyst and b) neutralization by addition of at least one organic sulfonic acid having a molecular weight of 250 to 1000 g/mol and at least one branched or unbranched alkyl substitution having at least four carbon atoms,n nwherein step b) is performed after step a). |
