To recognize good mechanical properties and water-resistance of a dental resin, dimethacryloxyethyl-1,1,6,6-tetrahydro-perfluoro-hexamethylene-1,6-dicarbamate (FDMHD) was newly synthesized. FDMHD initially was a white powder with m.p. 98.5-99.5°C. The copolymers of FDMHD and methyl methacrylate (MMA), FDMHD/MMA copolymers, were prepared to estimate the basic properties for dental resin materials. The compressive strength of FDMHD/MMA copolymers was almost the same compared with those of the copolymers of Bis-GMA or dimethacryloxyethyl-hexamethylene-1,6-carbamate (DMHD) and MMA. The bending, tensile, diametral tensile, impact strength and toughness of FDMHD/MMA copolymers containing 10.4 mol% FDMHD were higher than those of Bis-GMA/MMA copolymer, and the water sorption of FDMHD/MMA copolymers was lower than those of DMHD/MMA copolymers.
为了使牙科树脂具有良好的机械性能和耐水性，新合成了二甲基丙烯酰氧基乙基-1,1,6,6-四氢全氟己基-1,6-二碳酸酯（FDMHD）。FDMHD 最初是一种白色粉末，熔点为 98.5-99.5°C。制备了 FDMHD 和甲基丙烯酸甲酯（MMA）的共聚物 FDMHD/MMA 共聚物，以评估牙科树脂材料的基本性能。FDMHD/MMA 共聚物的抗压强度与 Bis-GMA 或二甲基丙烯酰氧基乙基-己基-1,6-碳酸酯（DMHD）和 MMA 的共聚物几乎相同。含 10.4mol%FDMHD 的 FDMHD/MMA 共聚物的弯曲、拉伸、直径拉伸、冲击强度和韧性均高于 Bis-GMA/MMA 共聚物，而 FDMHD/MMA 共聚物的吸水率低于 DMHD/MMA 共聚物。
