The fluoro-polyester resins(F-UPR) were synthesized from tetrafluoro-o-phthahic acid, maleic acid and propanediol in order to introduce the fluorine atom into the unsaturated polyester resin(UPR) chains and improve their properties. The result indicated that the product has viscosity 0.21 Pa·s (25℃), about half of that of the common unsaturated polyester resins (0.39 Pa·s, 25℃) and the contact angle between water and cured F-UPR was 64°. The water-resistant ability and acid-resistant ability of the resin were improved. The spectral and thermo-stability test results of the F-UPR showed that the UV-curing process of F-UPR could be completed within 40 min and the total mass loss of UV-cured F-UPR was 94.6% with thermodestruction temperature being 373℃.
