Synthetic Route
| Polysulfone is polymerized from dialkali metal salts of diphenols (such as bisphenol A disodium salt) and active aromatic dihalides (such as 4,4`-dichlorodiphenyl sulfone). The production of polysulfone usually adopts Farnham’s nucleophilic substitution reaction. From the perspective of polymer synthesis, the production process of polysulfone products almost adopts the nucleophilic substitution polycondensation route in the industrial synthesis method. The production method has a one-step method and a two-step method. The two-step synthesis reaction is to generate bisphenol A disodium salt by in-situ reaction of bisphenol A and alkali, and then nucleophilic with 4,4`-dichlorodiphenyl sulfone Substitution reaction. The one-step synthesis of polysulfone is to use potassium bicarbonate or potassium carbonate instead of sodium hydroxide to synthesize polysulfone. This method can shorten the synthesis steps, avoid the dehydration process, and shorten the reaction time. It has great potential in increasing the output, but the current production Still use the two-step method to complete. |
