The low viscosity fluorinated monomer, FHDDMA, was synthesized and used as a component of composite resin to improve the translucency and hydrolytic stability of photo cured composite resin. The refractive index of FHDDMA was smaller than that of TEGDMA and UDMA, and that of a mixture of FHDDMA and UDMA was close to that of silica filler. The contact angle of water on the FHDDMA polymer was higher than that on the TEGDMA and the UDMA polymers. The polymerization reactivity, translucency, depth of cure, and water sorption of the FHDDMA composite resin were superior to those of the TEGDMA resin. The friction coefficient of the FHDDMA composite resin was less than that of the TEGDMA resin. After undergoing the boiling water-immersion tests, the decrease of knoop hardness of the FHDDMA composite resin was less than that of the TEGDMA resin, and the bending strengths of the FHDDMA composite resin were almost same as those of the TEGDMA resin.
