摘要：
In this study, poly(phenylene sulfide ketone) [PPSK] was synthesized by reacting sodium sulfide with 4,4'-dichloro-benzophenone in N-methyl-2-pyrrolidinone. The effect of water, polymerization temperature, polymerization time, and stoichiometric ratio of monomers on the polymerization behavior of PPSK were investigated. From the study of polymerization behavior in the syntheses of PPSK with Phillips process, optimum polymerization condition was deterimined in view of inherent viscosity and conversion. There is no effect of additives such as sodium benzoate and lithum acetate. Thermal properties of PPSK synthesized were investigated with DSC and TGA in nitrogen atmosphere. T-g of PPSK was appeared at 110 degrees C and T-m was 335 degrees C (2nd run). The maximum degradation temperature is about 580 degrees C with a heating rate of 30 degrees C/min.
