Abstract
Ester group-containing dihydroxy compounds of reduced reactivity for use in polyurethane chemistry have the formula I ##STR1## where R is linear or branched alkylene of from 2 to 20 carbon atoms, substituted or unsubstituted cycloalkylene of from 5 to 10 carbon atoms or polyoxyalkylene of from 2 to 50 oxyalkylene groups in a random or blockwise arrangement and having from 2 to 4 carbon atoms in the alkylene radical, and are prepared by transesterification of alkyl hydroxypivalates with alkanediols, cycloalkanediols or polyoxyalkylene glycols.
