Real-time observations of bimolecular reactions are not currently feasible because the timing of collisions cannot be controlled more accurately than the reaction time.
One bimolecular reaction is chosen for analysis, as seen in Equation 5:
Figure 8 shows that hydroxyl radicals are indeed formed from the primary bimolecular reaction. The immediate initial increase in hydroxyl radical concentration leads to an accelerated crosslinking at the beginning of the Fenton reaction.
The reaction is initiated by decomposition of the peroxide, which leads to hydrogen abstraction from the polymer, followed by bimolecular reaction of two radicals to form a crosslink in the polymer.
This is the expected result, assuming that radical termination is fast in comparison to peroxide decomposition and that crosslinking can be described adequately as an elementary bimolecular reaction (20).
