Abstract
An ester-terminated copolyether glycol is prepared by copolymerization of tetrahydrofuran and an alkylene oxide or cyclic acetal in a reaction mixture containing, in addition to tetrahydrofuran and the alkylene oxide or cyclic acetal, (1) a polymeric catalyst which contains alpha-fluorosulfonic acid groups and (2) a precursor of an acyl ion such as acetic anhydride.
