Dependence of copolymer composition (m ) on content of monomers (M ) in the initial mixture for systems MMA-4FMA, MMA-8FMA, 4FMA-S, 8FMA-S [66] corresponds...

For MMA-8FMA and MMA-4FMA systems, dependence of the reaction rate on composition of the monomeric mixture (Figure 8.10, curves 1 and 2) [66] is linear in the whole range of copolymers composition studied, and for 4FMA-4FA and MMA-4FA systems, dependencies (Figure 8.10, curves 3 and 4) possess an inflection point at concentration in the initial mixture of, for example, 4FMA and 4FA of 0.30-0.40 mol% and 0.45-0.50 mol%, respectively, which is typical of the case, when r- < 1 and tj > 1 (or vice versa). 

Therefore, the copolymerisation rate for these systems is lower (Figure 8.10) than, for example, for MMA-4FMA and MMA-8FMA systems [24,66]. Experimental data obtained previously correlates well with data of quantum-chemical calculations (Table 8.7) [24, 66].
