DEGRADATION OF POLYACRYLIC ACID BY FENTON'S REAGENT

Polyacrylic acid (PAA) is degraded in an aqueous medium with Fenton's reagent. At long reaction times, 17 hours at 60°C, acrylic acid polymer suffer decarboxylation with Fenton's reagent. At the end of the degradation process, the polymeric product has physically changed, becoming an amorp...
