“…When polymerization occurs in a solvent with a low chain transfer rate (e.g., tert -butanol, water, benzene), a polymer with a high molecular weight is formed. Mitra et al found that radical transfer reactions by way of hydrogen atom abstraction from the organic substrates by the OH ▪ radicals were more favoured in aqueous media than in non-aqueous systems [55]. This information can be of key importance when working with eutectic systems containing water.…”

This review deals with two overlapping issues, namely polymer chemistry and deep eutectic solvents (DESs). With regard to polymers, specific aspects of synthetic polymers, polymerization processes producing such polymers, and natural cellulose-based nanopolymers are evaluated. As for DESs, their compliance with green chemistry requirements, their basic properties and involvement in polymer chemistry are discussed. In addition to reviewing the state-of-the-art for selected kinds of polymers, the paper reveals further possibilities in the employment of DESs in polymer chemistry. As an example, the significance of DES polarity and polymer polarity to control polymerization processes, modify polymer properties, and synthesize polymers with a specific structure and behavior, is emphasized.

synopsisQuantitative determination of endgroups in an acrylonitrile-methyl acrylate (90 : 10) copolymer polymerized with NaC10a-Na&30a redox system in aqueous solution was carried out by conductometric and dyeing methods for SOaH incorporated into polymer, x-ray analysis for S in polymer, and polarography for C1 in polymer. The number-average molecular weight was measured by osmometry. Determination of endgroups was done on both unfractionated polymer and fractionated polymer. On the average, 0.95 mole S and 0.71 mole SOaH per molecule were found in unfractionated polymer. For fractionated polymer, 0.68 mole S and 0.69 mole SOaH per molecule were found. A small amount of C1 was also found in both unfractionated polymer and fractionated polymer. The difference between results for the two polymers and polymerization kinetics are d i s CUSSed.
