Problems solved by technology

[0004] However, in the above-mentioned improved process and equipment, when the polymer material is reacting, due to the large molecular weight distribution span of the polymerized hydrocarbon of the polysulfone polymer material, there is no effective temperature control treatment for the reaction system, thereby increasing the risk of industrial production; After the polymerization reaction is over, after the solvent band is added with a drop of water to settle, the supernatant is extracted, and at the same time it must be settled again, and the supernatant is extracted and the supernatants on both sides are taken. This method has complicated steps and cannot effectively wash out the organic solvent, reducing the productivity
