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

I-Bisphenol fluorene yikhompawundi ye-bisphenol ene-Cardo skeleton structure, edityaniswe yi-condensation reaction ye-fluorenone kunye ne-phenol phambi kwe-catalyst ye-acidic. I-Bisphenol fluorene ikwayi-monomer kunye nesilungisi semathiriyeli esebenzayo yepolymer. Yimonoma okanye isilungisi esibalulekileyo sokudibanisa iimveliso zokujiya 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) i-fluoride isetyenziswa kakhulu njengendawo ephakathi kwi-organic synthesis, kwaye iphinda isetyenziswe kwi-synthesis ye-poly entsha (i-arylene ether). Ngenxa yesakhiwo sayo esiyingqayizivele, inokuphucula ukuxhathisa ukushisa kweepolymers kwaye ineempawu ezintle ze-optical kunye nokubunjwa. Ke ngoko, iye yaba yinto ekrwada okanye isilungisi sokwenziwa kwepolycarbonate entsha ekwazi ukumelana nobushushu, i-epoxy resin, kunye nepolyester.
