    Theoretical calculations have been performed to model the effects of a model Lewis acid, boron trichloride (BCl3) on the radical copolymerization of methyl methacrylate (MMA) and styrene (Sty). These calculations suggest that the high degree of alternation observed in the copolymer sequence distribution cannot be attributed to either ternary monomer complexes nor radical-monomer complexes. These complexes were not found to be sufficiently stable, particularly in the presence of competing solvation by toluene. However, this alternation can be satisfactorily explained via an enhanced cross-propagation mechanism, which originates from the matched donor/acceptor electronic character of the MMA(BCl3)/Sty system.
