Poly(arylene ether)s have been widely used as engineering thermoplastics due to their good mechanical properties, high thermal stability, and excellent resistance to hydrolysis and oxidation reaction. Also, fluorine-containing polymers are of considerable interest for optical and electronic applications owing to their low refractive index, optical loss, dielectric constant, surface energy, moisture absorption, and good thermal and chemical stability. In the study, we prepared new aromatic polymers with low refractive indices as well as high temperature resistances. The new polymers, poly(biphenylene oxide)s containing two pendent trifluoromethyl groups, were synthesized from AB-type monomers, 4’-hydroxy-4-fluoro-3,5- bis(trifluoromethyl)biphenyl. The resulting polymers are amorphous, and showed good physical properties. Details of the synthesis and properties of the polymer and the effect of the trifluoromethyl pendent groups will be presented. |
