| titleOfInvention | A kind of heat-resisting polyarylether resin of high fluorinated volume and preparation method thereof |
| abstract | A kind of heat-resisting polyarylether resin of high fluorinated volume and preparation method thereof, belongs to technical field of polymer materials.The present invention uses diazonium reactant salt first, and preparation has the (- CF containing trifluoromethyl of reactivity in the presence of Zn/Cu is common 3 ) double chlorine (or double fluorine) biphenyl structural double halogen monomers, above-mentioned double halogen monomers are then based on, in K 2 CO 3 、NaCO 3 In the presence of equal basic catalysts, with biphenol monomer pyrocondensation, novel high fluorinated volume (each repetitive unit contains 6 or 12 fluorine atoms) polyarylether resin is prepared.The high fluorinated volume polyarylether resin being prepared can be formed a film by solution casting method or form coating in silicon wafer, glass or metal surface.The polyarylether resin of prepared high fluorinated volume has high thermal stability, low refractive index, low-k, strong-hydrophobicity.It allows them to be applied to the fields such as optical waveguide material, low dielectric constant insulating material, efficient gas separation membrane material, non-sticking lining, hydrophobic coating and low refractive index materials. |
