Abstract

La presente invención se refiere a un proceso mejorado para la preparación de un polímero de acrilamida que contiene grupos hidroxámicos mediante la reacción en solución acuosa de un polímero de acrilamida con una sal de hidroxilamina a una proporción molar de hidroxilamina a grupos amida en el polímero de acrilamida de desde alrededor de 0.1 hasta alrededor de 2.0, en donde la mejora consiste en llevar a cabo la reacción a un pH de por lo menos alrededor de 8.0 y una temperatura que fluctúa desde alrededor de 20 hasta 100 grados C.
