Photochromic materials with stable properties during long-term use have a very broad application prospect. Herein, five kinds of spirooxazines (SO1-SO5) with antioxidant properties were successfully synthesized by blending and covalently bonding antioxidants. Then various photochromic polyacrylate laminating adhesives (PA1-PA7) with good fatigue resistance were prepared by incorporating spirooxazines into polyacrylate. Among them, this study used 2, 6 -di-tert-butyl-4-methylphenol (BHT) as the main antioxidant, and tris (2, 4-di-tert-butylphenyl) phosphite (168) as the auxiliary antioxidant. Upon UV activation, these PA films possessed superior photochromism and light responsiveness. Importantly, unlike traditional phys. blending photochromic polymers, SO2 was successfully covalently bonded into PA through reaction (PA6), effectively improving the fatigue resistance and thermal stability of the PA film. Doping with BHT, it further improved the photochromic properties of the compound film (PA7).
