New thioether glycidyl resins produced by condensation of bis(4‐mercaptomethylphenyl) ether and bis(4‐mercaptomethylphenyl)methane with epichlorohydrin were obtained by heterophase alkaline condensation in water and isopropyl alcohol solution. To define the optimal conditions of condensation, the following factors that influence the process were studied: the mole ratios of epichlorohydrin–mercaptan, alcohol–mercaptan, alkaline hydroxide–mercaptan. For all reaction products, yield, epoxide content, and chlorine content were determined. The structure of thioether glycidyl resins with the highest epoxide content was determined by elemental analysis and infrared and NMR spectra. The physical and chemical properties were defined. Some properties of the resins, cured chemically or thermally with different curatives, and thermal and mechanical properties of the cured compounds were determined.
