| titleOfInvention | A method of preparing polyaryl thioether sulfone |
| abstract | The invention discloses a kind of new methods for preparing polyaryl thioether sulfone, are related to polymeric material field, with aqueous vulcanized sodium, 4,4 '-dichloro diphenyl sulfones are raw material, using sodium hydroxide as auxiliary agent, using N-Methyl pyrrolidone as solvent, using Third monomer as chain extender, molecular weight is improved by the way that catalyst is added, the method that the present invention uses chain-extension polymerization, it is time-consuming shorter in the case where identical molecular weight polyisoprene aromatic sulfide sulphone resin is made, it is easier to realize, is substantially shorter process flow；A large amount of water is not added in the method provided by the present invention for preparing polyaryl thioether sulfone as conventional method into system, therefore synthesis pressure is lower under identical synthesis temperature, significantly reduces operational danger and production cost；The present invention is using Third monomer as chain extender, and type is more, and cost is relatively low, and chain extension mode purpose is stronger；In addition, the present invention carries out precipitation processing to poly arylidene thio-ester sulphone resin using water, precipitation is at low cost, effect is good, and product particle is more evenly. |
