| Abstract |
Polyphenylene sulfide (PPS) is a polymer with good chemical resistance, mechanical and thermal stabilities. Conventional polymerizing methods are the solution and melt polymerizations. The solution polymerization method is to obtain paradichlorobenzene (p-DCB), sodium sulfide (Na2S) or sodium hydrogen sulfide in a polar solvent under high temperature and pressure. This reaction produces sodium chloride and its removal is important. The other method, melt polymerization can be obtained at high temperature and high vacuum of 300 ℃ or higher and using para-diiodobenzene(DIB) and sulfur. Iodine, which is produced as a byproduct of melt polymerization, requires high vacuum and is difficult to remove. Sodium chloride and iodine, which are the byproducts of the conventional polymerization process, remain in the polymer, resulting in weakening of strength and properties. In this study, PPS containing less iodine was polymerized with sulfur and DIB in high-temperature solvent. It is also possible to control the content of sulfur. Sulfur content is PPS was analyzed by EA, and thermal properties of sulfur contents were confirmed by TGA and DSC. It was confirmed that various PPS polymerization was possible, and it was confirmed that the electrode could be used as an LI-S battery. |
