It turns out that particular meso-PCP+ structures involving primary carbocations are what slow down the chain-branching steps.
With this system, complexation of the Lewis acid coinitiator with the acetate group of IBEA dissociates the carbon-oxygen bond to produce a carbocation at the oxygen-stabilized secondary carbon atom of IBEA.
The carbocations do not readily form because of the poor electron donating capability of primary carbon atoms.
