Yintoni i-9,9-Bis(4-hydroxyphenyl)fluorene CAS 3236-71-3?

I-Bisphenol fluorene yi-bisphenol compound enesakhiwo se-Cardo skeleton, eyenziwe yi-condensation reaction ye-fluorenone kunye ne-phenol xa kukho i-asidi catalyst. I-Bisphenol fluorene ikwayi-monomer kunye ne-modifier yezinto ze-polymer ezisebenzayo. Yi-monomer ebalulekileyo okanye i-modifier yokwenza iimveliso ze-condensation ezifana ne-fluorene based epoxy resin, i-fluorene based benzoxazine resin, i-acrylic resin, i-polyester resin, i-polycarbonate, i-epoxy resin, i-polyester okanye i-polyether.

Isicelo

I-9,9-Bis (4-hydroxyphenyl) fluoride isetyenziswa kakhulu njengesixhobo esiphakathi kwi-organic synthesis, kwaye ikwasetyenziswa kwi-new poly (arylene ether). Ngenxa yesakhiwo sayo esahlukileyo, inokuphucula ukumelana nobushushu beepolymers kwaye ineempawu ezilungileyo zokukhanya kunye nobuchule. Ke ngoko, ibe yinto eluhlaza okanye i-modifier yokwenziwa kwe-polycarbonate entsha engatshisi ubushushu, i-epoxy resin, kunye ne-polyester.
