Water‐soluble photoresins based on azosulfonates

Abstract

Abstract Water‐soluble polymers with pendant azosulfonate groups were synthesized by radical copolymerization of 3‐vinylphenylazosulfonate with methyl methacrylate or styrene. The copolymerization parameters were determined for these systems. Furthermore, photoactive polymers were obtained by reaction of poly[(methacryloyl chloride)‐ co ‐(methyl methacrylate)] with azosulfonates containing phenolic or amino groups. Due to their solubility in water and their photocrosslinking behaviour, these polymers are attractive candidates for photoprinting and photoresist materials.
