9,9-Bis(4-(2-Hydroxyethoxy) phenyl) Fluorene is a white powdery substance, soluble in organic solvents such as toluene, absolute ethanol, acetone, ethyl acetate and dichloromethane. It is a new organic chemical raw material with high stability. It is mainly used to synthesize polymer monomers with excellent heat resistance, transparency and high refractive index (such as epoxy resin, polycarbonate, polyester, polyether or polyether). Ether, etc.), and these high refractive index polymers are mainly used in materials such as optical lenses, optical lenses, optical films, plastic optical fibers, optical disc substrates, heat-resistant resins or engineering plastics, and are in great demand all over the world . At present, it is very interesting in South Korea, Japan, Taiwan and the United States, and it is developing rapidly.
