TAGGED SCALE INHIBITING POLYMERS, COMPOSITIONS COMPRISING THE SAME, AND METHOD FOR PREVENTING OR CONTROLLING SCALE FORMATION

摘要

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