## Abstract Poly(__p__βphenylene sulfide) (PPS) oligomers were synthesized from sodium sulfide (SS) and pβdichlorobenzene (__p__βDCB) in hexamethylphosphoramide (HMPA) under atmospheric pressure. The effects of reaction time, temperature, and monomer ratio on end groups and molecular weight of PPS
Ultraviolet photoelectron spectra were measured for films of poly(pphenylene sulfide) (PPS) prepared by vacuum evaporation. The threshold ionization potential was determined to be 6.0 k 0.1 eV. The peaks in the photoelectron spectra are assigned by comparison with theoretical calculations, and the I
