PHASE TRANSFER CATALYZED METHOD FOR PREPARATION OF POLYETHERIMIDES

Polyether polymers, such as polyetherimides, are prepared by the reaction of a dihydroxy-substituted aromatic hydrocarbon alkali metal salt, such as bisphenol A disodium salt, with a bis(N-(chlorophthalimido))aromatic compound, such as 1,3- and/or l,4-bis(N-(4-chlorophthalimido))benzene, in a solven...
