Abstract:
     Using hexapposphamine as solvant, sodium phosphate as assistant, in the presence of the third component, hydrogen sulfide and p-dichlorobenzene (raw material) can be polymerized into linear macromolecular polybenzene thioether under ordinary pressrue. This method is characterized by:1) that H2S has cheap and wide resources: e.g. warte H2S gas in factory, sweetening sour gas from natural gas, waste H2S gas in the production of carbon disulfide, H2S produced from sulfurous iron ore. 2) that instruments needed are simple, and period of reaction is short while it has high quality, high percentage of products and low cost 3) making full use of waste gas.
