METHOD OF PREPARING POLYSULFIDE OLIGOMERS |
| 摘要 |
FIELD: synthesis of polysulfide oligomers. SUBSTANCE: method of preparing polysulfide oligomers from organic di- and polythiosulfates in aqueous medium, organic di- and polythiosulfates are reacted with alkali metal hydrosulfide at reagent molar ratio from 1:1.5 to 1:1.9 and at temperatures from 50 to 100 C. This makes it possible to increase desired product to 98% by using ecologically advantageous technology. EFFECT: more efficient preparation method. |
