Primary radical termination definition

Some quantum yields of radical polymerization (< >p for definition see Eq. (2b)) with the model monomer MM A are presented in Table 5. It is obvious that a variety of parameters acts on this value. Mainly, the participation of initiator molecules and of primary radicals on chain termination are responsible for the differences in the < >p-values. 

The kinetic chain length, v, is defined as the average number of monomers consumed by each primary radical. Obviously from this definition, the magnitude of the kinetic chain length will depend on the rate of the propagation relative to the termination rate, i.e..
