Polyether esters |
| abstract |
Polyether ester polymers of tetrahydrofuran and γ-butyrolactone or hexamethyleneoxide and γ-butyrolactone. The polymers are prepared by contacting the mentioned monomers in the presence a fluoride or chloride of antimony or a chloride of tin or titanium. The polymers can be used as components in the preparation of polyurethanes. |
