Abstract
The study explores the synthesis and structural characterization of oligomers obtained based on sodium polysulfide and epichlorohydrin, using modern spectral analysis methods. The main goal is to determine the molecular composition, functional group transformations, and structural features of synthesized oligomers through IR spectroscopy, UV-Vis spectroscopy, and NMR analysis. The results confirm that the polymerization reaction proceeds through nucleophilic substitution, resulting in the formation of flexible oligomeric chains containing polysulfide and ether fragments.
The obtained data contribute to the understanding of the structure–property relationship in sulfur-containing oligomers and provide a foundation for their application in corrosion protection and composite materials
