9,9-Bis(4-hydroxyphenyl)fluoreneCAS3236-71-3

Bisphenol fluorene is the monomer and modifier of functional polymer materials. It is a bisphenol compound with cardo ring skeleton structure. It is an important monomer or modifier for the synthesis of fluorene based epoxy resin, fluorene based Benzoxazine Resin, acrylate resin, polyester resin, polycarbonate, epoxy resin, polyester or polyether polycondensation products. Among them, fluorene based epoxy resin has excellent comprehensive properties such as humidity and heat resistance, dielectric property, mechanical property and chemical resistance, and has become an important monomer and modifier in high performance matrix resin materials, electronic packaging materials, high temperature resistant adhesives, high temperature resistant coatings and other aspects. But fluorene based epoxy resin has strong rigidity and poor toughness, so it needs to be toughened or blended with general epoxy resin.
