understanding the mechanism of breaking polyacrylamide

Understanding the Mechanism of Breaking Polyacrylamide. Random chain-scission seems to be the most efficient means of breaking PHPAM FRs. This study clearly demonstrates that RGBs degrade polyacrylamide FRs effectively, whereas NRGBs are not recommended under the same treatment conditions, even at significantly higher concentrations.
