Abstract WHERE A IS ALKYLENE AS DEFINED ABOVE R6 IS LOWER ALKYL OR HALOGEN. X IS 1 OR 2, Y IS 0 TO 2 AND X+Y IS 1 TO 3. WATER SOLUBLE SALTS OF THE ABOVE POLYMERS ARE ALSO DISCLOSED. THE STILBENE MOIETY IN SAID POLYMERS ACTS AS A BUILT-IN SENSITIZER FOR THE RADIATION SENSITIZATION OF THE SULFONAZIDO MOIETY. THE RADIATION-SENSITIVE POLYMERS ARE USEFUL IN A VARIETY OF WAYS INCLUDING MODIFICATION OF THE SURFACE OF -C-H CONTAINING POLYMERS, BONDING BASIC DYESTUFFS TO NON-DYE RECEPTIVE SUBSTRATES, PHOTOIMAGING AND THE LIKE ((R6)Z,(N3-SO2)Y-PHENYL)-NH-COO-A- WHERE CNH2N AND (R)X ARE AS ABOVE. AND (II) THOSE WHICH ARE CHARATERIZED BY A COMBINATION OF TWO RECURRING UNITS IN THE SAME MOLECULE ONE OF THE UNITS BEING THAT PRESENT IN THE POLYMERS (I) AND THE OTHER UNIT HAVING THE SAME GENERAL FORMULA ABOVE WHERIN R1 IS AS ABOVE DEFINED. ONE OF R2 AND R3 IS HYDROGEN AND THE OTHER IS: -CNH2N-OOC-NH-C6H4-CH=CH-C6H4-(R)X WHEREIN R1 IS LOWER-ALKOXY OR PHENYL, ONE OF R2 AND R3 IS HYDROGEN AND THE OTHER IS: -(CH(-COO-R2)-CH(-COO-R3)-CH(-R1)-CH2)- WHERE CNH2N IS ALKYLENE. R IS ALKOXY AND X IS 1TO 3. AND RADIATION SENSITIVE POLYMERS DERIVED THEREFROM. ARE DESCRIBED. THE RADIATION SENSITIVE POLYMERS INCLUDE (1) THOSE WHICH ARE CHARACTERIZED BY A RECURRING UNIT REPRESENTED BY FORMULA: HO-CNH2N-COO-NH-C6H4-C6H4-CH=CH-C6H4-(R)X STILBENES OF THE FORMULA:
