Abstract
New experimental visible-light cured soft resins were prepared by combining 4 kinds of fluoroalkyl methacrylate monomers with a vinylidene fluoride/hexafluoropropylene copolymer, or a vinylidene fluoride/tettrafluroethylene/hexafluoropropylene copolymer. Some properties of the resins prepared were examined to determine their value as a soft denture liner material. Water contact angles were more than 90 degrees in all cases and increased with the increase in the number of fluorine atoms in the fluoroalkyl groups. Hardness (JIS A) was less than 50 for the softes resin. Water sorption after 10 weeks was 3-4.5 wt %. Solubility 0.1-0.3 wt% and amount of residual monomer 0.2 wt% were very low. The properties of these new experimental resins were comparable or superior to the commercial soft materials available.
