Low molecular weight materials contained in PPS resin were obtained by extracting PPS powder exhaustively with xylene and examined by solid probe mass spectroscopy.Six families of oligomers have been identified in the extract.Cyclopenta (p-phenylene sulfide) (Ⅰ) and cyclohexa (p-phenylene sulfide) (Ⅱ) have been isolated from PPS by extraction and recrystallization,and characterized.
