The first carbenium ion I undergoes hydrogen shifts to form carbenium ions II, III, V and rearranges to IV by methyl shift.
The propagating carbenium ion combines with counterion
The cation radical interacts with the free-radicals from PE molecule fragment through electron transfer that to be deoxidized, inducing the formation of carbenium ions and increasing the reaction course of cationic polymerization.
The phenonium ions interact with carbenium ions in a manner of electron transfer, resulting in reduction of cationic polymerization course ultimately.
Some of these carbenium ions (or their diazoprecursors) obviously do not alkylate DNA (initiation of a tumor), if the electrical charge distribution would not favor SN 1- or SN 2- reactions in organisms.
