Abstract: REDOX OLYMERS, WHICH, IN THE OXIDIZED CATIONIC FORM, CONTAIN REPEATING UNITS OF THE FORMULA:

-CH2-C6H4-CH2-(PYRIDINIUM-1,4-YLENE)-(PYRIDINIUM-4,1-

YLENE)-

ARE READILY REDUCED, EITHER CHEMICALLY OR ELECTRICALLY, AND CHANGE COLOR FROM COLORLESS TO INTENSE BLUE-VIOLET. THE REDUCED FORM IS READILY OXIDIZED WITH OXYGEN IN AIR OR DISSOLVED IN SOLUTION SO THAT IT IS USEFUL FOR DEOXYGENATING GASES OR LIQUIDS WITH THE COLOR CHANGE BEING A SELF-INDICATOR OF THE REDOX STATE OF THE POLYMER. THESE COMPOSITIONS CAN BE MADE SO THAT THEY ARE SOLUBLE OR INSOLUBLE IN AQUEOUS MEDIA AND FORM POLYELECTROLYTE COMPLEXES WITH CATION EXCHANGE RESINS.
