To realize good mechanical properties and water resistance of a dental resin, novel di-α-fluoroacrylates with polyfluoroalkyl aromatic backbone were studied. The monomers were 2,2-bis(4-α-fluoroacryloxy phenyl)propane, 2,2-bis(4-α-fluoroacryloxy phenyl) hexafluoropropane, and 1,3-bis(2-α-fluoroacryloxy-2-hexafluoropropyl)benzene. The copolymers of the monomers and methyl methacrylate (MMA) were excellent in hardness, Izod impact strength, abrasion resistance, and water resistance, and showed similar values of compressive, diametral tensile, tensile, and bending strength compared with copolymers prepared from the corresponding dimethacrylate derivatives and MMA.
为了实现牙科树脂的良好机械性能和耐水性，研究了具有聚全氟烷基芳基主链的新型二-α-氟丙烯酸酯。单体为 2,2-双（4-α-氟丙烯酰氧基苯基）丙烷、2,2-双（4-α-氟丙烯酰氧基苯基）六氟丙烷和 1,3-双（2-α-氟丙烯酰氧基-2-全氟丙基）苯。这些单体和甲基丙烯酸甲酯（MMA）的共聚物具有优异的硬度、Izod 冲击强度、耐磨性和耐水性，与由相应的二甲基丙烯酸酯衍生物和 MMA 制备的共聚物相比，其压缩强度、直径拉伸强度、拉伸强度和弯曲强度值相似。
