CHEMICAL TECHNOLOGIES
20 Decorative coatings based on coloured epoxy oligomers — Doctor of Chem. Sci., Prof. Mognonov D. M., Doctor of Tech. Sci., Prof. Zayakhanov M. E., Associate Prof. Mangadaev A.M., Candidate of Tech. Sci., Associate Prof.Dorzhieva E. V. Candidate of Tech. Sci., Associate Prof. Balkhanova E. D.
Abstract: Colored synthetic resins obtained by grinding resin and pigments (dyes) in ball mills have low light resistance and are characterized by migration of pigment to the surface. To obtain them, a large amount of pigment (dye) is required. Much better performance is typical for structurally colored resins in which the dye or pigment is chemically bonded to the polymer macromolecule. In this paper, the possibility of obtaining colored decorative paints based on structurally colored binders, which were obtained by joint polycondensation of diphenylolpropane, epichlorohydrin and small amounts (0.1–0.5% by weight) of glycidyl esters of 1-aminoanthraquinone (GEAA) or diglycidyl ether of 1.5-diaminoanthraquinone (DGEAA), is considered.
Glycidyl esters of aminoanthraquinone (GEAA and DGEAA) were synthesized by the N-alkylation of 1-aminoanthraquinone or 1.5-diaminoanthraquinone with epichlorohydrin.
The resulting structurally colored oligomers are viscous liquids with a molecular weight from 400 to 700 (cryoscopy in benzene), colored from orange to red.
Structurally colored epoxy oligomers are characterized by intense coloring, high light resistance while maintaining good mechanical properties.
Keywords: UV curing, radiation polymerization, acrylic urethane film-forming materials, monomers, photoinitiators.

Abstract. The work presents the full cycle of development of an interoperable zinc-containing primer based on two epoxy resins with different molecular weights: from selecting components to determining the properties of the formed coatings. The main physical and mechanical properties of the resulting coatings are presented, as well as the results of welding tests.
Keywords: shop primer, non-removable surgical coatings, zinc-protective shop primers, epoxy oligomers.

PHYSICO-CHEMICAL RESEARCH
32 Adsorption of oligomers with different functional groups from solutions in xylene on carbon black samples — Candidate of Chem. Sci. Konishchev M. A., Candidate of Chem. Sci. Aristov B. G., Candidate of Chem. Sci. Smrchek V. A., Candidate of Chem. Sci. Kienskaya K. I.
Abstract. The adsorption from solutions in xylene of special additives containing different functional groups - acidic, basic and quaternary ammonium - was studied on carbon black samples used in the domestic coatings industry. It was found that in the case of carbon black, adsorption is due only to dispersion interactions. In the case of microporous samples, the adsorption value of additives is several times greater. It is shown. that the filling of micropores begins already in the region of low concentrations by volumetric filling without capillary condensation and the plateau on the isotherms corresponds to the completion of this process. The maximum value of adsorption is determined by the available volume of the porous space of the sorbent.
Keywords: carbon black, functional group, isotherm, adsorption, monolayer, acidic additive, basic additive, porosity, mesoporous carbon black, microporous carbon black, micropore, capillary condensation.
