| Abstract: | Thioetherglycidyl resins produced by condensation of bis(4-mercaptophenyl)ether and bis(4-mercaptophenyl) methane with epichlorohydrin were obtained by heterophase alkaline condensation. To define the optimal conditions of condensation, the following factors that influence the process were studied: the kind of organic phase and the mole ratios of epichlorohydrin:mercaptan, alcohol:mercaptan, and alkaline hydroxide:mercaptan. For all syntheses yield and the epoxide content were found. The structure of thioetherglycidyl resins with the highest epoxide content was determined by elementary analysis, infrared IR, and NMR spectra. The physical and chemical properties were also defined. The investigations covered the determination of some properties of resins, cured chemically or thermally with different curatives and thermal and mechanical properties of the cured compounds. |
