Degradation of high molar mass poly(ethylene glycol), poly(2-ethyl-2-oxazoline) and poly(vinyl pyrrolidone) by reactive oxygen species

The development of the apparent molar mass of different poly(ethylene glycol), poly(2-ethyl-2-oxazoline) and poly(vinyl pyrrolidone) upon incubation with hydrogen peroxide and different concentrations and catalytic amounts of CuSO4 was followed used gel permeation chromatography.
