The synthesis and optical properties of polyesters with pendant fluorinated phenoxy groups were examined. The polyaddition of bisphenol AF diglycidyl ether (1) with fluorine-containing terephtalates (2a-f) was carried out with tetrabutylphosphonium chloride (TBPC) as the catalyst in chlorobenzene to afford the corresponding polyesters with number-average molecular weights (M-n's) ranging from 15,200 to 30,000 in 88-96% Yields. Furthermore, the polyaddition of 1 with isophthalate 2g and phthalate 2h also produced high-molecular-weight polyesters with M-n's = 22,700 and 22,600 in 88 and 84% yields, respectively. The linear relationship was observed between the fluorine contents and refractive indices of the obtained polyesters.
