“…It has also been noted that higher values of IF would be regarded as an indicative of the non-selective template binding of the NIPs than improved imprinting efficiency of the MIPs. 27 These data show, in correlation to the rebinding the higher power polymers performed worse while lower powers were comparable. This indicated the presence of an equivalence of both the selective and non-selective binding sites present within the MIPs, with the percentages rebound being higher at lower concentrations suggesting that high affinity pockets fill up first.…”

“…The thermal decomposition rate of AIBN in 36 solvents was measured by different authors , and shown to be solvent-dependent with an overall variation in the rate constant of a factor of up to 4 when the solvents change from nonpolar to strongly polar. However, different values have been reported for the Arrhenius parameters of solvents in previous studies. − …”

In this work, the effect of the solvent type on microwave (MW)-assisted decomposition of 2,2′azobis(isobutyronitrile) was investigated by online monitoring of the reaction kinetics in various solvents: n-butanol, dimethyl sulfoxide, dimethylformamide, and n-propanol. The study showed that MW irradiation accelerates the reaction rates, but it does not affect the kinetic law (first order) and mechanism of the reaction. Furthermore, the Arrhenius parameters were found to be higher than their thermal counterparts, depending on the MW power density (P) as well as to the solvent type. On the other hand, two new properties were proposed to investigate the solvent/MW effects: a solvent property (S) defined by means of Hansen solubility parameters and the relaxation time of the solvent (τ). According to experimental results, solvents with high S and with an optimum τ value are favorable for an enhanced MW effect on chemical reaction kinetics, pointing to specific molecular structures for solvent candidates.

“…During the runs, the Fluoroptic (FO) sensor (accuracy±0.2 °C, ATC-FO-300008 type, Zu electronic, Italy) was dipped in the reactor in a glass capillary sheath. By external circulation of 1,4-dioxane as coolant between jacketed glass reactor and cooling bath, continuous and constant MW energy was applied under isothermal conditions as in our previous studies [2–4] . So, our MW experimental system differs from the literatures which use the cooling system by “air cooling“ [5–8] while applying discontinuous MW power [9–11] .…”

This article contains original experimental data, figures and methods to the study of Microwave-assisted emulsion polymerization of styrene under the frame of “Enhanced Microwave Synthesis” (EMS), has been examined to investigate the advantages of Microwave (MW) power use in emulsion polymerization (Ergan et al., Eur. Polym. J. 69, 2015, 374–384). For comparative purpose, MW and conventional heating (CH) method experiments were conducted under similar conditions. By externally cooling the reaction vessel with 1,4-dioxane, constant and continuous MW power was successfully applied at isothermal condition during the polymerization. Here we give the MW power calibration data of MW-experimental system, the complete set of the experimental polymerization data and the analysis data obtained from different polymer characterization test devices (GPC, DSC and Viscometer).
