Synthesis and characterization of novel 1,2,3-triazole-bridged oxime polyurethanes obtained from an isomannide derivative. Macedonian Journal of Chemistry and Chemical Engineering, 40(1), 75-87. doi:10.20450/MJCCE.2021.22201857-55521857-5625https://doi.org/10.20450/MJCCE.2021.2220https://hdl.handle.net/20.500.12428/4427Polyurethanes (PUs) are synthesized by the reaction of diisocyanates and diols and are widely used in furniture foams, thermal insulation, coatings, and adhesives. In this work, a 1,2,3-triazole-bridged dioxime (compound 6) as a diol source was synthesized from isomannide via tosylation, azidation, and cyclization-addition and used in the syntheses of new PUs. A new carbohydrate-based linear P-1 was syn-thesized by the reaction of 6 and 1,6-hexamethylene diisocyanate (1,6-HMDI). Besides, three new linear PUs (P-2, P-3, and P-4) were synthesized by the reaction of 6, isomannide compound (used in different molar ratios), and 1,6-HMDI. The thermal properties of the new PUs were determined by thermogravime-try (TG), their molecular structures were characterized by FTIR, 1H- and 13C-NMR, and the molecular weights of some polymers were determined by GPC/SEC. Additionally, the surface characteristics of the synthesized PUs were examined via scanning electron microscopy (SEM).eninfo:eu-repo/semantics/openAccessAttribution-NonCommercial 3.0 United States1,2,3-triazole1,6-hexamethylene diisocyanateAzideDioximeIsomannidePoly(oxime-urethane)PolyurethaneArticle401758710.20450/MJCCE.2021.2220Q4WOS:0006815156000092-s2.0-85109129671
