| titleOfInvention | A kind of synthetic method of the high transparency polysulfone resin of the substituted phenol containing cycloalkyl group |
| abstract | The invention discloses a kind of synthetic method of the high transparency polysulfone resin (PSU) of substituted phenol containing cycloalkyl group; using molar ratio as 1: 14; 4 ' dichloro diphenyl sulfones and bisphenol-A are reaction monomers; in the reaction kettle of nitrogen protection; heating is stirred after adding organic solvent; reaction monomers are added sequentially, salt forming agent is added after monomer all dissolving, divides aqua, stirring heating, when salt-forming reaction 1~2 is small；Heat up after the completion of reaction, add 0.1~5% cycloalkyl group substituted phenol, 4~5 hours of constant temperature polymerisation, obtain polymerization mucus；It will be got product after the cooling of polymerization mucus, crushing, washing, drying.The present invention introduces cycloalkyl group substituted phenol in polymer molecular chain, destroys polymer chain regularity, reduce crystallinity, prepare hydroxy-end capped high transparency polysulfone resin from molecular structure level.The product that the invention is synthesized both had remained the original excellent properties of polysulfones, more have high transparency advantage concurrently, there is more preferable application prospect and very big market value. |
