Formation of epoxy groups

10 FORMATION OF EPOXY GROUPS Epoxy groups (2.13) can be formed by the following reactions  

Epoxy groups exhibit a broad IR spectrum in the range of 1000-1250/cm. 

The formation of epoxy groups in polydienes is very much dependent on the structure of the photo-oxidized polymer for example, in the case of pure polybutadiene, it is very low [572], but in styrene-butadiene rubber (SBR) it is very high [292].

In ozonation, a partial double bonds breakage in the robber macromolecules that leads to the macroradicals formation occurs (Fig. 17.1). Ozone molecules are attached to the point of the robber double bonds breakage with the formation of epoxy groups [4] ...
