| titleOfInvention | A kind of high thermal stability blocks the Industrialized synthesis method of biphenyl contenting structure ketone-grouped resin |
| abstract | The invention discloses the Industrialized synthesis method that a kind of high thermal stability blocks biphenyl contenting structure ketone-grouped resin.It is so that with hydroquinones, '-biphenyl diphenol and 4,4 ' difluoro benzophenones or 4,4 ' difluoro triphen diketone are reaction monomers, with high boiling organic solvent as solvent, with alkali carbonate as salt forming agent, asymmetric aromatic ketone radical derivative carries out polymerisation for end-capping reagent, obtains polymerization mucus；Powder will be ground into after polymerization mucus cooling, solvent and by-product salt are removed with organic solvent, deionized water boiling washing again after filtering, biphenyl contenting structure ketone-grouped resin is obtained final product after drying.It is catalyst that the present invention individually uses alkali metal sodium carbonate, and not only blocks effect with preferable after addition end-capping reagent, and system does not occur depolymerization phenomenon, and the end-blocking biphenyl contenting structure ketone-grouped resin for obtaining has high high-temp stability. |
