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

I-Bisphenol fluorene iyinhlanganisela ye-bisphenol enesakhiwo se-Cardo skeleton, ehlanganiswe ukusabela kwe-condensation ye-fluorenone ne-phenol phambi kwe-catalyst ene-acidic. I-Bisphenol fluorene iphinde ibe yi-monomer nesilungisi sezinto ezisebenzayo ze-polymer. Kuyi-monomer ebalulekile noma isilungisi sokuhlanganisa imikhiqizo yokujiya efana ne-fluorene based epoxy resin, i-fluorene based benzoxazine resin, i-acrylic resin, i-polyester resin, i-polycarbonate, i-epoxy resin, i-polyester noma i-polyether.

Isicelo

I-9,9-Bis (4-hydroxyphenyl) i-fluoride isetshenziswa kakhulu njengemaphakathi ku-organic synthesis, futhi isetshenziswa nasekuhlanganiseni i-poly entsha (i-arylene ether). Ngenxa yesakhiwo sayo esiyingqayizivele, ingathuthukisa ukumelana nokushisa kwama-polymers futhi inezici ezinhle ze-optical kanye nokubunjwa. Ngakho-ke, isiphenduke into eluhlaza noma isilungisi sokuhlanganiswa kwe-polycarbonate entsha emelana nokushisa, i-epoxy resin, ne-polyester.
