| Abstract: | This is a method of producing crystal linear high molecular weight poly p phenylene sulfide (HMWPPS) resins by mixing hydrogen sulfide which is produced from the acid gas of desulphurization factory of natural gas, sodium hydroxide, p dichlorobenzene and additive sodium phosphate, and carrying out the polycondensation in hexamethyl phosphoryl triamide (HPTA) solvent for 4 to 6 h under normal pressure. This method has obvious advantages as simple equipment, easy operation, high activity, stable solvent, high product yield, low cost and it is suitable for large scale industrial production. |
