Analytical methods for the determination of hydroperoxide groups

Hydroperoxide (OOH) group concentration can be determined by a number of analytical methods, such as  

The advantages and limitations of these methods in solid polymers have been reviewed [683]. Table 10.7 gives a comparison of the different methods of titration with the determination of hydroperoxide groups by a spectroscopic method in which SO2 is used. (cf. section 10.17.2.3) The sulphur dioxide (SO2) method can be carried out easily, but with some polymers secondary effects are observed which perturb the measurements. 

The iodometric method can be used only when the hydroperoxides are thermally stable, up to 80°C. On the other hand, the thiocyanate method is
