Kinetic Model of Radical Polymerization

If the transfer reaction to the initiator and monomer is neglected, the overall mechanism of polymerization can be expressed as follows  

The mole balance equations for batch reactors are written for the species I2,1, Pi, 

Assuming that the quasi-steady-state approximation (QSSA) is valid, the concentration of the intermediate species I can be found from Eq. (5.3.3)  

In radical polymerization, the slowest reaction is the dissociation of initiator molecules. As soon as a primary radical is produced, it is consumed by the reactions of Eq. (5.3.1). Thus, the concentration off is expected to be much less than that of P that is.

To verify the kinetic model of radical polymerization presented in the last section, the following assumptions must be confirmed ...
