Under the action of light, polymers that can reversibly change color are called photochromic polymers, which belong to polymer materials. According to Krongauz’s definition of a photochromic polymer, a photochromic polymer means that the photochromic pigment molecules are chemically bonded to large molecules. In the strict sense, photochromic… Read More »Definition of photochromic polymers
Preparation method(1) Preparation of acrylic prepolymer. Benzoyl peroxide was evenly mixed with styrene, methacrylic acid and methyl acrylate in proportion, and 20% of the mixture was added to the four-mouth flask with butanol, evacuated and filled with N, and the temperature was raised to 93℃. The remaining 80%… Read More »Preparation method of acrylic thermochromic paint
