The influence of monomer content on the viscoelasticity, water sorption and solubility of experimental fluorinated soft lining materials was investigated. Changes in the viscoelastic properties of the materials were also examined after thermal cycling. Four fluorinated soft lining materials containing different amounts of methoxy diethylene glycol methacrylate (MDGMA) and tridecafluorooctyl methacrylate (13FMA) were prepared. The viscoelastic displacement for specimens containing 13FMA was found to be less than that without 13FMA (p0.05). Water sorption and solubility The water sorption of the treated soft lining materials ranged from 7.38 µg/mm3 for F18 to 45.8 µg/mm3 for F0 (Fig. 7). The specimen without 13FMA (F0) had the largest water sorption and those for the other specimens significantly decreased in the order F6, F12 and F18 (p
