    Abstract: The present invention provides a highly efficient process for manufacturing copolyether glycol having a mean molecular weight of from about 650 to about 5000 dalton by polymerization of tetrahydrofuran and at least one alkylene oxide in the presence of an acid catalyst and at least one compound containing reactive hydrogen atoms. More particularly, the invention relates to a process for manufacturing copolyether glycol which comprises recycle to the polymerization reaction step of at least a portion of the oligomeric cyclic ether which is co-produced with the copolyether glycol, said process exhibiting an Space Time Yield value of greater than about 0.9.
