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.
