“…40 and 61-85). Several years earlier, Benson and North (40) had reported similar results for MMA, and this dependence was later abundantly confirmed by others (66)(67)(68)(69)(70)(71)(72)(73)(74)86). The viscosity can either be varied using different solvents with inherently different viscosities, or alternatively, various amounts of polymer can be dissolved as a viscosity modifier.…”

“…This was actually already the case in some of the MMA studies in different solvents, as mentioned above (40,(66)(67)(68)(69)(70)(71)(72)(73)77), as not all these solvents dissolve pMMA (polymethylmethacrylate) equally well (95). This complexity arises from the fact that, if one solvent is replaced by another (or, alternatively, as soon as some polymer has been formed), the thermodynamic properties of the solution change simultaneously.…”

“…As reported in the literature, many solvents affect not only the termination rate constant but also the growth rate constant kp of MMA18, 19). In order to find out whether such a mechanism is acting in this system, it is necessary to determine kp for several monomer mixtures.…”

The kinetics of the free radical copolymerization of diethyl maleate (M1 ) with methyl methacrylate (M2) was studied in bulk at 60°C with azoisobutyronitrile (AIBN) as initiator. The reactivity ratios of the system were determined by means of H NMR spectroscopy. The obtained values show that diethyl maleate is not only unable to homopolymerize (rI2 = 0) but also displays a very low tendency to incorporate in the polymer chain (rZ1 = 370) under the present conditions. Molecular weight measurements showed that a normal, although very slow growth reaction involving diethyl maleate takes place. Therefore, chain transfer could be neglected in the kinetic analysis. The dependence of the initiation rate constant on the monomer feed was analysed by means of the inhibition method. An equation for describing the observed dependence of polymerization rate on feed composition was derived taking into account the influence of solution viscosity on the termination rate constant (diffusion theory). a) Part of Ph.

This investigation reports the synthesis of poly(methyl methacrylate) via activators regenerated by electron transfer atom transfer radical polymerization (ARGET ATRP) and studies the effect of solvents and temperature on its polymerization kinetics. ARGET ATRP of methyl methacrylate (MMA) was carried out in different solvents and at different temperatures using CuBr 2 as catalyst in combination with N,N,N ′ ,N ″ ,N ″ -pentamethyldiethylenetriamine as a ligand. Methyl 2-chloro propionate was used as ATRP initiator and ascorbic acid was used as a reducing agent in the ARGET ATRP of MMA. The conversion was measured gravimetrically. The semilogarithmic plot of monomer conversion versus time was found to be linear, indicating that the polymerization follows first-order kinetics. The linear polymerization kinetic plot also indicates the controlled nature of the polymerization. N,N-Dimethylformamide (DMF), tetrahydrofuran (THF), toluene, and methyl ethyl ketone were used as solvents to study the effect on the polymerization kinetics. The effect of temperature on the kinetics of the polymerization was also studied at various temperatures. It has been observed that polymerization followed first-order kinetics in every case. The rate of polymerization was found to be highest (k app = 6.94 × 10 −3 min −1 ) at a fixed temperature when DMF was used as solvent. Activation energies for ARGET ATRP of MMA were also calculated using the Arrhenius equation. K E Y W O R D Satom transfer radical polymerization, kinetics, methyl methacrylate, solvent effect
