The rate of fl-scission of benzoyloxy radicals is such that in most polymerizations initiated by these radicals both phenyl and benzoyloxy end groups will be formed (Scheme 3.4). A reliable value for the rate constant for p-xcission would enable the absolute rates of initiation by benzoyloxy radical to be estimated. Various values for the rale constant for p-scission have appeared. Many of the early estimates are low. The activation parameters (in CCI4 solvent) determined by Chateauneuf et a(.m are log]0 A = 12.6 and Ea = -35.97 kJ mol 1 which corresponds to a rate constant of 9xl06 s 1 at 60 °C. 

The Coleman-Fox two state model describes the situation where there is restricted rotation about the bond to the preceding unit (Scheme 4.3). If this is slow with respect to the rate of addition, then at least two conformations of the propagating radical need to be considered each of which may react independently with monomer. The rale constants associated with the conformational equilibrium and two values of Pirn) are required to characterize the process. 

Mahabadi and O Driscolm considered that segmental motion and center of mass diffusion should be the dominant mechanisms at low conversion. They analyzed data for various polymerizations and proposed that k, J should be dependent on chain length such that the overall rale constant obeys the expression ... 

Hold the recycle toluene flow rale constant by adjusting fuel to the furnace. 

We will indicate the order of the chemical reaction with a subscript, so k2 is the rale constant of a second-order reaction.

Potential flow is approached for the 0.7-mm bubbles and the larger single-bubble collection efficiencies dramatically increase the predicted rate constants compared to Stokes flow. For a given oil drop size the calculated rale constants decrease relative to the predicted values indicating that all... 

The next step was to determine efficiency as a function of reject ratio while holding the inlet flow rale approximately constant. A series of runs has been completed with reject ratios in the range of 0.1 to 17.0%. 

An absorption (1030 nun) found in the near-infrared spectrum of this complex arises from a mixed valence transition. Light-induced meial-to-metal charge transfer was predicted by Hush56 for systems of this type before it was observed experimentally. Further, his theory relates the energy of absorption to that required for thenral electron transfer (hv = 4 x Ec) and from this it is possible to calculate the thermal electron transfer rale constant (5 x (08 s-1).57...
