| titleOfInvention | Improved polyether glycol manufacturing process |
| abstract | The present invention relates to an improved process for manufacturing polyether and copolyether glycols by polymerization of a reaction mixture comprising at least one tetrahydrofuran or at least one tetrahydrofuran and at least one other cyclic ether, for example, an alkylene oxide, in the presence of a particular perfluorosulfonic acid resin catalyst comprising a copolymer of tetrafluoroethylene (TFE) or chlorotrifluoroethylene (CTFE) and a monomer of the formula CF 2 = CF - O - CF 2 - CF 2 - SO 2 F. |
