Determination of chain scission from spectroscopic measurements

11 DETERMINATION OF CHAIN SCISSION FROM SPECTROSCOPIC MEASUREMENTS [Pg.473]

The rate constant for random chain scission (fc ) is given by equation [1292] [Pg.473]

Cq and c, are the concentrations of a given chromophore, before and after irradiation, respectively. [Pg.474]

Random chain scission may also be represented in terms of average degrees of polymerization by the equation [Pg.474]

From eqimtions 10.80 and 10.81 it appears that the average degree of chain scission (P,) is given by expression [Pg.474]
