| titleOfInvention |
Copolyether glycol manufacturing process |
| abstract |
The present invention relates to a continuous process for manufacturing copolyether glycols with high incorporation of alkylene oxide by polymerization of tetrahydrofuran and at least one alkylene oxide in the presence of an acid catalyst, at least one compound containing reactive hydrogen atoms, and a specific diluent or solvent. More particularly, the invention relates to a diluent or solvent-assisted continuous process for manufacturing copolyether glycols with high incorporation of alkylene oxide. |
