Saloutin // Russian Journal of Applied Chemistry. - 2010. - Vol. 83, № 4. - P723-727 : табл., граф. - Bibliogr. : p. 723-727 (24 ref.) Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): POLYMERS -- EPOXY-ANHYDRIDE POLYMERS -- OXIRANES -- POLYFLUOROLAKYL-SUBSTITUTED OXIRANES -- CURING Аннотация: Epoxy-anhydride polymers based on N,N,O-triglycidyl-p-aminophenol and isomethyltetrahydrophthalic anhydride were synthesized in the presence of new active modifiers, polyfluoroalkyl glycidyl ethers. The kinetics of the reactions of the modifiers with the anhydride were studied by differential scanning calorimetry and IR spectroscopy. The physicomechanical characteristics, glass transition points, and water absorption of the polymers were determined. \\\\Expert2\\nbo\\Russian Journal of Applied Chemistry\\2010, v. 83, N 4, p.723-727.pdf |
M 78 Modification of adhesive materials based on epoxy oligomers with fluorinated organic compounds [Electronic resource] / A. V. Pestov, I. S. Puzyrev, A. Mechaev, D. I. Vichuzhanin, P. P. Matafonov // Russian Journal of Applied Chemistry. - 2014. - Vol.87, №4. - С. 474-479. - Bibliogr. : p. 478-479 (48 ref.) Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): THERMAL ANALYSIS -- ORGANIC DERIVATIVES -- EPOXY RESINS Аннотация: N-Containing perfluoropentanoic acid derivatives were used as modifying additives to commercial epoxy resins. As shown by differential thermal analysis, the fluorinated organic derivatives exhibit catalytic activity in curing of epoxy resins. The following characteristics of the adhesive compounds in the cured state were determined: degree of swelling, gel fraction content, ultimate shear strength of the adhesive joint, adhesion to low-carbon St.3 steel and AMg-6 aluminum-magnesium alloy, and corrosion-protective properties with respect to these materials \\\\expert2\\nbo\\Russian Journal of Applied Chemistry\\2014, v. 87, N 4, p.474-479.pdf |
