Abstract
A polymer composition includes components selected from: (i) at least one a poly(aryl ether ketone) (PAEK), (ii) a poly(ether sulfone) (PES), (iii) a reactive poly(ether sulfone) (rPES), (iv) a reactive poly(aryl ether ketone) (rPAEK), (v) an acid component, and (vi) at least one alkali metal carbonate. Preferably, the polymer composition is free or substantially free of solvent. A method includes melt mixing the components of the polymer composition.
