Once the primary variables were obtained, numerous secondary variables were also calculated such as overall conversion, monomer A and B conversions, polymer composition from the moles of A and B in the copolymer, and number average molecular weight. The latter was obtained by dividing the mass of monomers A and B in the polymer by the moles of polymer. 

Data of Nomura and Funita (12). The predictive capabilities of EPM for copolymerizations are shown in Figures 8-9. Nomura has published a very extensive set of seeded experimental data for the system styrene-MMA. Figures 8 and 9 summarize the EPM calculations for two of these runs which were carried out in a batch reactor at 50 °C at an initiator concentration of 1.25 g dm 3 water. The concentration of the seeded particles was 6x10 dm 3 and the total mass of monomer was 200 g dm 3. The ratio of the mass of MMA to the total monomer was 0.5 and 0.1 in Figures 8 and 9 respectively. The agreement between the measured and predicted values of the total monomer conversion, the copolymer composition, and the concentration of the two monomers in the latex particles is excellent. The transition from Interval II to Interval III is predicted satisfactorily. In accordance with the experimental observations, EPM predicted no new particle formation under the conditions of this run.

The time to tQ is the time for the wood-monomer mass to reach oven or curing temperature at T5. During the period of constant temperature, the induction period, the inhibitor is being removed by reaction with the free radicals. Once the inhibitor is eliminated from the monomer and wood, the temperature rises to a maximum which corresponds to the peak of the exothermic polymerization reaction. Polymerization continues to completion although at a decreased rate and the temperature returns to that of the curing chamber. The time to the peak temperature depends upon the amount of catalyst present, the type of monomer, the type of crosslinker, and the ratio of the mass of monomer to that of the wood. The wood mass acts as a heat sink. Figure 4 illustrates the effect of increased Vazo catalyst on the decrease in time to the peak temperature, and the increase in the peak temperature(10)...

Fig. 11 illustrates how well the thickness growth rate, GR/FM, in 40 kHz and 13.5 MHz glow discharge of methane and n-butane, can be expressed as a function of the composite energy input parameter W/FM. Regardless of the mass of monomer, flow rate, and...

In Chapter 6, we defined the centres which scatter neutrons or photons as being (respectively) nuclei or electrons. In this chapter, the set of all the centres belonging to a monomer will be considered as a unique scattering centre. This more economical definition is justified by the fact that, in the interval (0, qm ) where we study the behaviour of scattering cross-sections, the length q x is always large as compared to atomic distances. Let rai be the position vector of the centre of mass of monomer i. Then, suppose... 

The theoretical is calculated by assuming that all the inimer molecules in the reaction act solely as monofunctional initiator and not as a branching agent. This quantity is calculated from the mass of monomer (m ) and the moles of inimer ( j) in the reaction as described by the following equation ...
