This review summarizes the literature data on the physicochemical properties of oligo(ethylene glycol) (meth)acrylates. The influence of the structure of these macromonomers on their solubility, tendency to association in solutions, interfacial activity, reactivity in reactions of acid- and base-catalyzed hydrolysis, radical homo- and copolymerization is considered.

Fe Catalysts

Vulcan XC-72R-supported Fe catalysts have been synthesised for the electroreduction of CO2to high-added value products. Catalysts were obtained by the polyol method, using ethylene glycol as solvent and reducing agent. Prior to the metal deposition, Vulcan was subjected to different oxidation treatments in order to modify its surface chemistry and study its influence on the physicochemical and electrochemical properties of the catalysts, as well as on the product distribution. The oxidation treatments of the supports modify their textural properties, but do not affect significantly the physicochemical properties of catalysts. However, DEMS studies showed that the carbon support degradation, the distribution of products, and the catalytic activity toward the CO2electroreduction reaction depend significantly on the surface chemistry of the carbon support.

Ni2P, MoP, and NiMoP supported on MAS (10) were successfully prepared using acid and base regulators. The intrinsic role of pH and synergic factors has altered the physicochemical properties of the catalysts, which are responsible for HDO activity.

We prepared new and scalable, hybrid inorganic–organic step-growth hydrogels with polyhedral oligomeric silsesquioxane (POSS) network knot construction elements and hydrolytically degradable poly(ethylene glycol) (PEG) di-ester macromonomers by in situ radical-mediated thiol–ene photopolymerization.

Anionic Part

Task-specific RTILs of symmetrical N-methylimidazolium rings linked to an oligo (ethylene glycol) chain (cationic part) and bis-trifluoromethane sulfonimide (anionic part) were synthesized, and the physicochemical properties with catalytic activity were determined.
