ABSTRACT
Assuming these reactions in the general scheme of s-transformations, described in Section 4.3.3, and suggesting the steady state condition for all reagents in supemanopore, the following relation can be simply deduced:
d[rs• J = 20kos-kls[rs"J-k2s[rs"]- k4s i[Rs"][IHJ-kss i[Rls"][IHJ = dt ' ' = 28kos-2kts[rs"]- 2k2s[rs"] = 0
and
(5.1.1)
With respect to equation (5.1.1), the previous expression for the degradation rate (4.3.15) which characterizes a system possessing no IH is reduced to the following one:
(5.1.2)
Dibenzoyl peroxide concentration change (C) in reacting CTA and PC films is described by an exponential equation:
C = Coexp(- kit), (5.1.3)
where ki is the effective rate constant characterizing the chain reaction of BP decomposition and depended on concentrations Co and Ci. The effect of kinetic equation (5.1.3) is demonstrated by BP expenditure curves plotted in semilogarithmic coordinates in Figures 5.1 and 5.2.
