monomer I with various compositions of methyl methacrylate (MMA) were prepared and characterized. The glass transition temperature values obtained for the copolymers were between 120 and 150 °C. The refractive indices of the copolymers were in the range of 1.4350–1.4872 at 532 nm. They were thermally stable (up to 297–323 °C), and their water absorptive properties were greatly decreased, compared with
合成了聚[1,1,1,3,3,3-六氟-2-(五氟苯基)丙-2-基甲基丙烯酸酯(I)],并合成了单体I与各种组成的甲基丙烯酸甲酯(MMA)的共聚物被准备和表征。对于该共聚物获得的玻璃化转变温度值为120至150℃。共聚物在532 nm处的折射率在1.4350–1.4872范围内。与纯PMMA相比,它们具有热稳定性(最高297–323°C),并且吸水性能大大降低。
