【Abstract】 In this article the equipment, raw material, process flow sheet, major parameters, cost accounting and product property related to the pilot one—step synthesis of polyethersulfone (PES) by 4, 4’-dichloro-diphenyl sulfone and alkali sodium salt of diphenol S were introduced. The results showed that the equipment for this new technology was simple, reliable, and easy to operate; the property index of the equipment came up to the standards of the equipments of same kind at abroad. The pilot synthesis provided industrial production of PES with desin basis.更多还原
