ABSTRACT:
Polyether polycarbonate diols based on 1,6-hexanediol and having a molecular weight of from 500 to 12,000 are made by etherifying 50-100 mole % 1,6-hexane-diol in the presence of 0-50 mole % of specified diols and reacting the resultant polyether with a compound selected from diarylcarbonates, dialkyl carbonates, dioxolanones, hexanediol bischlorocarbonic acid esters, phosgene and urea. These diols are particularly useful in the production of polyurethanes having improved physical properties.
