New experimental visible-light cured soft resins were prepared by combining a low molecular weight vinylidene fluoride/hexafluoropropylene copolymer(2-6FL), or vinylidene fluoride/tetrafluoroethylene/hexafluoropropylene copolymer(2-4-6FL)with 2, 2, 3, 3-tetrafluoropropyl α-fluoroacrylate(4FFA), or 2, 2, 3, 3, 4, 4, 5, 5-octafluoropentyl α-fluoroacrylate(8FFA).Some properties of the resins prepared were measured to determine whether they would be candidate material for soft denture liner.Water contact angle was 90〜92° with 4FFA, and 90〜94° with 8FFA.The resins combined with 2-4-6FL were sufficiently soft:42〜46(JIS A hardness)in 4FFA, and 33〜39 in 8FFA.Generally the hardness decreased by 5〜10 with the use of a low molecular weight of fluoropolymer.Water sorption after 10 weeks was 0.8〜1.2% in 2-6FL/4FFA, 1.3〜1.7% in 2-6FL/8FFA, about 1% in 2-4-6FL/4FFA, and about 2% in 2-4-6FL and 8FFA.Solubility was 0.4〜0.5% in 2-6FL/4FFA, 0.3〜0.4% in 2-4-6FL/4FFA, 1.5〜1.9% in 2-6FL/8FFA, and 1.1〜1.5% in 2-4-6FL/8FFA.Amount of residual monomer was very low, and the maximum was 0.1%.Tensile strength of the resins was reduced to 40〜70% of that of the similar resins obtained in the previous study.Thus softer resins could be prepared by using lower molecular weight fluoropolymers.
