Chain transfer does not affect the overall rate of polymerization but does affect the molecular weight distribution of polymer products. It is related to the efficiency of synthesizing the polymer within a designated range. Complication in Chain Termination by disproportionation: Termination may occur by recombination or Recombination: CH2 CH2 + CH2CH2 CH2CH2CH2CH2 Disproportionation: CH2 CH2 + CH2CH2 CH CH2 + CH2CH3 Recombination strengthens the chain length, whereas disproportionation gives short chains.

The term kd is the rate constant of the decomposition of peroxide, ki is the rate constant of the thermal initiation of the biradical, kr is the rate constant of the first-order recombination of radicals from the peroxide, and ka is the rate constant of the reaction of these radicals with monomer: Propagation: kp M + M ð2:5Þ M2 Chain transfer to monomer: ktr,m Mn + M Polymer + M ð2:6Þ Chain transfer to solvent: ktr,a Mn + S Polymer + kp′ S S M,kp′ + M SM Chain transfer to initiator: ki Mm + I Polymer + R ð2:7Þ where kp is the rate constant of propagation, ktr is the rate constant of transfer, and ki is the rate constant of the chian transfer to the initiator.
