A polymer composition includes at least two different polymers independently selected from poly (aryl ether ketone) (PAEK), poly (aryl ether sulfone) (PAES), polyarylene sulfide (PAS), and Polyetherimide (PEI); and about 0.05 wt.% to about 2 wt.% of at least one alkali metal carbonate. Preferably, the polymer composition is free or substantially free of solvent. One method includes melt mixing at least two different polymers independently selected from the group consisting of poly (aryl ether ketone) (PAEK), poly (aryl ether sulfone) (PAES), polyarylene sulfide (PAS), and Polyetherimide (PEI); and about 0.05 wt.% to about 2 wt.% of at least one alkali metal carbonate to form the compatibilized polymeric composition. |
