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

I-Bisphenol fluorene iyinhlanganisela ye-bisphenol enesakhiwo samathambo e-Cardo, ekhiqizwa yi-condensation reaction ye-fluorenone ne-phenol lapho kukhona i-acidic catalyst. I-Bisphenol fluorene iphinde ibe yi-monomer kanye ne-modifier yezinto ze-polymer ezisebenzayo. Iyi-monomer ebalulekile noma i-modifier yokwenza imikhiqizo ye-condensation 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-fluoride engu-9,9-Bis (4-hydroxyphenyl) isetshenziswa kakhulu njengengxenye ephakathi kokwenziwa kwezinto eziphilayo, futhi isetshenziswa nasekuhlanganisweni kwe-poly entsha (arylene ether). Ngenxa yesakhiwo sayo esiyingqayizivele, ingathuthukisa ukumelana nokushisa kwama-polymer futhi inezakhiwo ezinhle zokukhanya kanye nokwakheka okuhle. Ngakho-ke, isibe yinto eluhlaza noma i-modifier yokwenziwa kwe-polycarbonate entsha engamelani nokushisa, i-epoxy resin, kanye ne-polyester.
