A new fluorinated poly (ether amide) bearing xanthene group was prepared from 9, 9-bis[4-(2-trifluoromethyl-4-aminophenox-y) phenyl]xanthene (BTFAPX) with 9, 9-bis[4-(4-carboxyphenoxy) phenyllxanthene(BCAPX)in the presence of triphenyl phos-phate and pyridine (Py). The polymer had the weight-average molecular weight (M_w) of 69, 000 and number-average molecular weight (M_n) of 39, 000, showed the glass transition temperature (T_g) of 267℃, 5% weight loss temperature(T_d5)over 460℃ both in N₂ and air, and char yield of 62% at 800℃ in N₂. This polymer was amorphous and readily soluble in amide-type solvents such as N, N-dimethylacetamide (DMAc), and even in m-cressol, Py and tetrahydrofuran (THF) at room temperature, and exhibited tensile strength of 74 MPa, elongation at break of 6%, tensile moduli of 2.2 GPa. The polymer had low dielectric constant of 3.69 (100 Hz), low moisture absorption of 0.56%, and high transparency with an ultraviolet-visible absorption cut-off wavelength at 334 nm.
