9,9-Bis(4-hydroxyphenyl)fluorene CAS 3236-71-3
Bisphenol fluorene ndi chinthu cha bisphenol chokhala ndi kapangidwe ka mafupa a Cardo, chomwe chimapangidwa ndi condensation reaction ya fluorenone ndi phenol pamaso pa acidic catalyst. Bisphenol fluorene ndi monomer komanso modifier ya zinthu zogwirira ntchito za polima. Ndi monomer yofunika kwambiri kapena modifier popanga zinthu zophatikizana monga fluorene based epoxy resin, fluorene based benzoxazine resin, acrylic resin, polyester resin, polycarbonate, epoxy resin, polyester kapena polyether.

9,9-Bis (4-hydroxyphenyl) fluoride imagwiritsidwa ntchito kwambiri ngati gawo lapakati pa kapangidwe ka organic, ndipo imagwiritsidwanso ntchito popanga poly yatsopano (arylene ether). Chifukwa cha kapangidwe kake kapadera, imatha kupititsa patsogolo kukana kutentha kwa ma polima ndipo ili ndi mawonekedwe abwino komanso mawonekedwe abwino. Chifukwa chake, yakhala chinthu chopangira kapena chosinthira kupanga polycarbonate yatsopano yosatentha, epoxy resin, ndi polyester.
Kawirikawiri amanyamula mu 25kg/ng'oma, ndipo amathanso kupangidwa mwamakonda.
