摘要

Methods for Preventing corrosion and Scale deposition in aqueous media.The methods used in water soluble Polymers tienenfuncionalaidades derivatized amide Earrings, to inhibit the fouling.Lospolu00edmeros are distributed mu00e9ricas repeated units represented by the formula (i),Where R1 is selected from the group consisting of hydrogen and alkyl of C1 - 3, P and q are integers from 1 to 10; R2 and R3 are selected from the group consisting of hydrogen, alkyl andC1 - 3; het1 and het2 are selected from the group consisting of nitrogen and poroxu00edgeno; R4 is selected from the group consisting of hydrogen and alkyl of C1 - 20; R5 and R6 are selected from the gruPO formed porhidrogeno, carboxylate, c1-3 alkyl and cycloalkyl Group 3 to 6 carbon Atoms formed by the Union of R5 and R6 as a ring.
