| Abstract: | The poly-sulphur,called also the insoluble sulphur(IS),is the linear polymer of sulphur,and is mainly used as the top quality vuleanizing agent of the rubber. The formation mechanism of poly-sulphur, production process,and the choice of the stabilizing agent, the cooling medium and the extractant in the process of manufacture of poly-sulphur by molten method were introduced. The qualitative standards in control and the method of analysis were briefly introduced, too. It was predicted that the molten method would play a vital role in production in the future. |
