Abstract

Métodos para prevenir la corrosion y deposicion de incrustaciones en medios acuosos. Los métodos utilizan polímeros solubles en agua que tienenfuncionalaidades amida derivatizadas pendientes, para inhibir las incrustaciones. Lospolímeros tienen unidades méricas repetidas distribuidas,representadas por la formula (I), en donde R1 se selecciona a partir del grupo formado por hidrogeno y alquilo de C1-3; p y q son numeros enteros de 1a 10; R2 y R3 se seleccionan a partir del grupo formado por hidrogeno y alquilo de C1-3; Het1 y Het2 se seleccionan a partir del grupo formado poroxígeno y nitrogeno; R4 se selecciona a partir del grupo formado por hidrogeno y alquilo de C1-20; R5 y R6 se seleccionan a partirdel grupo formado porhidrogeno, carboxilato, alquilo de C1-3 y un grupo cicloalquilo de 3 a 6 átomos de carbono formado por la union de R5 y R6 como un anillo.
