Abstract: Polymeric color pH indicators are prepared which are insoluble in the measured aqueous medium and show a certain range of color change. These polymeric indicators are the product of copolymerization of a hydrophilic comonomer, selected from esters, amides and N-substituted amides of acrylic and methacrylic acid, with 0.1- 30 wt.% of a comonomer. The comonomer forms the pH-indicating color center by a subsequent coupling with a suitable diazonium salt or a passive component. Vinylic monomers comprising an aromatic system in the molecule are suitable as the functional comonomers. The indicators are prepared by radical copolymerization of the comonomers either in a suspension or in a solution, followed by the subsequent coupling with a diazonium compound, or diazotizing and coupling with a passive component, to obtain the pH-indicating sites of polymer.
