| Abstract: | This paper reports preliminary results of the crystallization and the thermal degradationbChavior of high viscosity polypbenylene sulfide ( PPS ) of the sulfur method by thermoanalysis.The results are compared with PPS of the Na_2S method,showing that the crosslinking structure,the thermal stability and the crystalline behavior of PPS of the sulfur method are affected by theimpurity. |
