Initiation is followed by the propagation step with the addition of more monomers to the carbenium ion in a rapid exothermic reaction.

The propagation step involves H: shift and :CH3 group shift to form tertiary carbenium ion which is more stable and abundantly available during propagation.

The extent of rearrangement during cationic propagation will depend on the relative stabilities of propagating and rearranged carbenium ions and relative rates of propagation and rearrangement.
