ABSTRACT:
The invention comprises a process for synthesizing a high molecular weight hydroxamic acid polymer and other substituted amides onto a polyacrylic acid or a polymethacrylic acid latex backbone by reacting a stable, inverse polyacrylic acid or polymethacrylic acid latex with hydroxylamine sulfate, in the case of hydroxamic acid, or other primary amines, to produce the high molecular weight substituted amides. The invention further comprises a method of clarifying Bayer process liquors using the substituted amides produced by the process.
