ABSTRACT:
Poly(ester-ethers) are produced by the copolymerization of tetrahydrofurans and cyclic carboxylic anhydrides using selected metal perfluoroalkylsulfonates and related compounds as catalysts. The resulting copolymers are useful as intermediates for monomers for use in other polymerizations.
