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 ℃.展开更多
