FIELD: polymer materials.
SUBSTANCE: invention relates to use scale formation polymer to prevent and to control formation of scale in water containing systems. Invention is directed to develop scale formation inhibiting labeled polymers, which can be detected in presence of such compounds as antioxidants or in non-regenerated oil. Invention proposes labeled copolymers wherein labeled units are derived from monomer of formula X2C=CYY', in which X, the same of different, represent hydrogen atom or С1-С4-alkyl group, Y hydrogen atom or С1-С4-alkyl group, Y' is group of formula -L-Arom with L being covalent bond or bivalent organic linking group optionally containing heteroatoms and Arom being a group including optionally substituted naphthalene, anthracene, or phenanthrene moiety. A composition containing above-defined polymers as well as a method for preventing and controlling formation of scale such polymers are also proposed.
EFFECT: enabled detection of proposed polymers in presence of other substances.
