  • Modified, water-soluble polymers containing amide groups reacted with xanthydrol and other dyes
    Patent number: 4813973
    Abstract: Water-soluble, amide group containing polymers such as polyacrylamide are modified, to render them easy to detect, by reacting the polymer in aqueous solution with organic dye molecules which can form stable carbo-cations reversibly in water. The labelled polymers can then be detected spectrophotometrically. An example of a suitable dye molecule is 9-xanthydrol.
