Clearly, to minimize formation of unfavorable free polymers during surface-initiated polymerization, chain initiation has to shift from bicenter mechanisms (one initiator forms two primary active species, such as thermal homolysis of azobisbutyronitrile, A1BN or benzoyl peroxide, BPO) to monocenter counterparts (one initiator forms only one primary active species, such as transition metal-catalyzed atom transfer radical polymerization, ATRP).
In this reaction mechanism, PCB absorbed photon, activated and dechlorinated by homolysis.
ROO* and HO* were generated by the thermal homolysis of 20 mM 2-2'-azo-bis-(2-methylpropionamidine)-dihydrochloride and from an Fe ascorbate Fenton reaction (Regoli and Winston 1999), respectively.
Ketones undergo homolysis by either fragmentation or photo cleavage and hydrogen abstraction.
