The Reuse of Oligomeric Materials from the Waste of Poly(phenylene sulfide) Production

Abstract:

In order to reuse the waste originated from poly(phenylene sulfide) (PPS) production in stead of combustion, the oligomeric materials in the waste were recovered as raw materials. The recovered materials, then, were used to react with sulfur in molten state to produce polymeric resin. The structure and thermal property of oligomeric materials and their derived polymer were characterized by elemental analysis, infrared spectroscopy, X-ray diffraction and differential scanning calorimetry. The results showed that oligomeric materials are a series of PPS oligomers, and their derived polymer is poly(arylene sulfide)s (PAS). The thermal transition temperatures of obtained PAS are higher than those of PPS oligomers, which are attributed to the increase of molecular weight. It is desired that the yielding PAS has potential applications as plastic, coating, or filler materials.
