TL;DR: In this article, an immobilized macromolecular copper catalysts were prepared by modification of nitrile groups in acrylonitrile, vinyl acetate and divinylbenzene terpolymer using aminoguanidine carbonate and subsequent complexation with copper(II) nitrate.

TL;DR: In this paper, the catalytic activity of Cu(II) complexes with Schiff base immobilized on the synthesized supports were tested in the oxidation reaction of 2,6-di-tert-butylphenol (DTBP) to diphenoquinone (PQ) with tertbutylhydroperoxide.

TL;DR: In this paper, a series of acrylic resins with aminoguanidyl groups were prepared by aminolysis of nitrile groups in acrylonitrile, vinyl acetate and divinylbenzene terpolymer using aminogenidine bicarbonate and hydrazine and subsequent substitution with thiourea/ethyl iodide (TEI) mixture.

TL;DR: In this article, a new modification direction of acrylonitrile, vinyl acetate and divinylbenzene terpolymers (A, B) was presented, and properties of all obtained resins such as water regain, nitrogen content, amine and carboxyl group concentration and sorption properties towards Cu(II) from nitric acid solutions were determined.

TL;DR: In this article, the results of synthesis of anion exchanger with guanidyl end groups are presented in the form of reaction of primary amino groups attached to resins with S -methylthiourea gave the anions with up to 2.6 mmol of ligands per gram of resin.
