Poly(ionic liquid)s: Synthesis, properties, and application

Abstract: The overview of the published data on a new class of polyelectrolytes—the so-called polymeric ionic liquids or poly(ionic liquid)s—is presented The peculiarities of their synthesis and the factors affecting their molar masses, solubility, ionic conductivity, electrochemical stability, and thermal properties are discussed The mainstreams in the application of poly(ionic liquid)s and materials formed on their basis are illustrated by specific examples

A review on synthesis of value added products from polyethylene terephthalate (PET) waste

Abstract: Many research papers have been contributed by several authors for making PET waste recycling economically and ecologically more viable. Recycling of PET waste was started in last two decades. Most of the authors are devoting their time in getting economically viable solution for development of methods based on either mechanical or chemical recycling. Some success has been obtained in development of chemical recycling methods which provides value added products from PET waste. However, different products developed by chemical recycling have not provided economically enough and reliable methods of recycling of PET waste.

Synthesis and properties of polymeric analogs of ionic liquids

Abstract: A number of methacrylate ionic monomers with different structures and mobilities of ionic centers were synthesized. The free-radical polymerization of these monomers in solution affords high-molecular-mass (M sD = 0.5 to 2.5 × 106) thermally stable (T dec > 170°C) polyelectrolytes or cationic or anionic “polymeric ionic liquids.” The conductivities of polycation- and polyanion-derived coatings are (7.4 × 10−10)−(7.6 × 10−7) and (4.9 × 10−10)-(1.6 × 10−7) S/cm (25°C), respectively. As exemplified by poly(1-[3-(methacryloyloxy)propyl]-3-methylimidazolium bis[(trifluoromethanesulfonyl)imide]), the molecular mass and glasstransition temperature of the polymer affect the ionic conductivity of the film coating. The transition from linear polyelectrolytes to crosslinked systems based on ionic monomers and poly(ethylene glycol dimethacrylate) 750 leads to the formation of elastic films featuring satisfactory strength, reduced glass-transition temperatures (−8 to +15°C), and increased ionic conductivity (up to 3.2 × 10−6 S/cm (25°C)).

Reversible addition-fragmentation chain-transfer polymerization: Fundamentals and use in practice

Abstract: Modern approaches to the synthesis of tailor-made macromolecules by radical polymerization proceeding through the reversible addition-fragmentation chain-transfer mechanism are considered. The mechanism of this process and the experimental and calculation methods for determining its main kinetic parameters are discussed. Particular emphasis is placed on the problems of designing copolymers of various microstructures, including random, gradient, and block copolymers.

Atom-transfer radical polymerization with Ti(III) halides and alkoxides

Abstract: Ti(III) halides and butoxide complexed with mono-, di-, and tridentate ligands were studied in the atom-transfer radical polymerization (ATRP) of styrene. An important advantage of titanium compounds is that Ti(IV) ions in the highest and air-stable oxidation state are colorless, thereby ensuring the absence of coloration in the final polymer. A better polymerization control was attained under conditions providing the enhanced reactivity of Ti(IV) intermediates due to the presence of ligands with a lower donor ability. When a complex of TiCl 3 and 1,2-bis(hexylthio)ethane was used as a catalyst, the styrene polymerization showed the kinetic and molecular mass features inherent to ATRP.
