| titleOfInvention | A kind of preparation method of multimercapto hyperbranched polysulfide based on lipoic acid |
| abstract | The invention discloses a preparation method of polysulfhydryl hyperbranched polysulfide based on lipoic acid. Add lipoic acid and reagents containing triple bonds and hydroxyl groups into tetrahydrofuran, stir for 5 minutes, add N,N'-dicyclohexylcarbodiimide and 4-dimethylaminopyridine, and react at 10~25°C for 3 After ~24 hours, a product containing disulfide bonds and triple bonds is obtained; then dissolved in tetrahydrofuran, then adding a reducing agent and water, and reacting at 10~25°C for 5~24 hours, to obtain a product containing both sulfhydryl groups and triple bonds. product; the prepared product containing both thiol and triple bonds is dissolved in N,N-dimethylformamide, and after adding a photoinitiator, it is irradiated under a 500~2000W ultraviolet lamp for 5~60 minutes to carry out thiol- yne click chemical reaction, that is, the preparation of lipoic acid-based multimercapto hyperbranched polythioether. The method of the invention is low in cost because of its simple preparation process and easy-to-obtain raw materials, and is suitable for large-scale popularization. |
