Abstract

A tricomponent system, constituting monomer (methyl methacrylate, MMA), higher oxidation state transition-metal catalyst (FeBr₃) and a ligand (triphenylphosphine, PPh₃), MMA/FeBr₃/PPh₃ system without external initiator (alkyl halide) has been studied extensively with different spectroscopic analyses. To figure out the mechanism, a series of explicit model reactions were conducted with a molar ratio of [MMA]₀/[FeBr₃]₀/[PPh₃]₀ = 200/1/n (n = 0.1–3.0) at 80 °C, and the corresponding polymerization behaviors were investigated. Combined with theoretical deduction and spectroscopic evidences, the composition of the in-situ generated initiators was gradually confirmed, which were redox products of FeBr₃ and PPh₃.
