Isotactic Polypropylene (C3H6 MW=42g/mol), a thermo plastic is
synthesized using bulk polymerization. For a monodisperse sample
(PDI=1) the bigger molecule(higher degree of polymerization)
contain the same total mass of the polymer sample than the smaller
molecules(lower degree of polymerization). For a polydisperse
sample the MW fractions do not contain the same mass.
Flexlife is the capability of polymeric material to withstand
repeated bending without fracture. The Z average MW (Mz) is a
measure of flexlofe as well as the predominance...

Propose a detailed, step-by-step mechanism for the
reaction pathway shown below:
I have the answer, but I do not understand as to the reasoning
behind this. Since when can you break a single bond to form the
large ring?
A better explanation would be helpful. Thank you!
