, p. 825 - 830 (1998)
The Diels-Alder cycloaddition copolymerization of a bis(diene) with ionizable bis(dienophiles) via a cation radical mechanism has been accomplished using tris(4-bromophenyl)aminium hexachloroantimonate as a catalyst in dichloromethane solvent. The reactions occur at 0°C and yield Diels-Alder polymers of Mw up to ca. 10,000 and a polydispersity index ca. 2.
Mechanistic Distinctions between Cation Radical and Carbocation Propagated Polymerization

The polymerization of bis[4-(1-propenyl)phenyl] ether in the presence of tris(4-bromophenyl)aminium hexachloroantimonate is found to occur by competing cation radical and carbocation pathways. These pathways involve, respectively, cyclobutanation and linear addition. Methods for favoring each mechanistic type are proposed and explored.
