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.
