Abstract Two novel kinds of high transparency films (PAAdEMA and P2AdEMA) derived from isocyanatoethyl methacrylate and 3-amino-1-adamantanol (AAD) or 2-adamantanol were synthesized. The structures and properties of the monomers and corresponding polymers were determined by Attenuated total reflection Fourier transform infrared (ATR-FTIR), hydrogen nuclear magnetic resonance (1H-NMR), gel permeation chromatography (GPC), thermogravimetric analysis (TGA), differential scanning calorimeter (DSC) and Ultraviolet–visible (UV–vis) spectroscopy. Introducing adamantane at side chains of the polymer improves the thermal stability, light transmission and ultraviolet stability. The degradation temperatures at 5% weight loss of PAAdEMA and P2AdEMA were approximately 25℃ and 55℃ higher than that of pristine poly (methyl methacrylate) (PMMA), respectively. The average spectral transmittances of the 18 μm thick films were above 90% in the wavelength range of 280–380 nm and 99% in the wavelength longer than 380 nm, exhibiting excellent transparency. After irradiating the films at wavelength of 254 nm for 84 h, the transmittances of PAAdEMA around 290 nm changed and still were above 80%, compared with 66% for pristin PMMA.
