| abstract |
The invention relates to tagged scale-inhibiting polymers, to compositions comprising said polymers, and to a method for preventing or controlling scale formation in systems comprising said fluids. The tagging units are units deriving from a monomer having formula X2C=CYY', wherein X, which is identical or different, is a hydrogen atom, or a Cl-C4 alkyl group, Y is a hydrogen atom or a C1-C4 alkyl group, Y' is a group having formula -L-Arom, wherein L is a covalent bound or a divalent organic linking group optionally comprising. heteroatoms, and Arom is a group comprising at least two conjugated aromatic rings, preferably at least three, said rings comprising conjugated carbon atoms, and, linked to said carbon atoms, hydrogen atoms or substituants. |
