Copolymerization of Tetrahydrofuran and Cyclic Anhydride |
| abstract |
Poly (ester-ethers) are prepared by copolymerizing tetrahydrofuran and cyclic carboxylic anhydrides using selected metal perfluoroalkylsulfonates and related compounds as catalysts. The resulting copolymers are useful as intermediate compounds for monomers used in other polymerizations. |
