ABSTRACT:
The present invention discloses new compounds of the formula 4,4'-di-(.omega.-hydroxyalkoxy)-biphenyl), wherein the alkoxy group contains from 8 to 13 carbon atoms. The use of the new compounds, in particular the compound 4,4' -di-(11-hydroxyundecanoxy)-biphenyl, in the synthesis of segmented polyurethanes, results in products having a particularly advantageous profile of properties.
