P. Matusche et al., WATER-SOLUBLE AND PHOTOACTIVE COPOLYMERS CONTAINING AMIDIC ARYLDIAZOSULFONATE GROUPS, Journal of macromolecular science. Pure and applied chemistry, A34(1), 1997, pp. 201-209
Photoactive polymers could be synthesized by copolymerization of methy
l methacrylate and sodium-(4-methacryloylaminophenyl)-diazosulfonate w
hich became water soluble at high azo content. Determination of the co
polymerization parameters revealed an almost ideal copolymerization be
havior of the two monomers. The photoactivity of the azo chromophore c
ould be further increased by introduction of two methoxy substituents
into the aromatic unit which renders these polymers more suitable for
application as photo resins.
