Explain the following for the chaingrowth polymerization:
a It is found that polymerization progresses even without an initiator when the vinyl monomers are
exposed to high temperatures.
i How does the initiation occur in this case? Please explain briefly.
ii Model the rate of polymerization rp Find the average molecular weight of the polymer.
b Assume that the temperature of polymerization is increased from deg C to deg C for pure styrene, and
the polymerization is carried out to completion.
i Do you expect the equilibrium monomer concentration to reduce or increase?
ii Calculate the equilibrium monomer concentration as a function of temperature.
