Usage: Organic chemical raw material, as a potent conductive material, liquid crystal display industry in the extensive research in recent years. Polyimide by hydroxy hydroxy acid and the grafting reaction of the hydroxy with photosensitive polyimide, and by IR, NMR to determine the photosensitivity of the hydroxyl polyimide structure. The synthetic hydroxy polyimide liquid crystal alignment layer as used in liquid crystal display, the demonstrated good thermal stability. 4, the cosmetics: hydroxy cinnamic acid on the tyrosinase enzyme and two single-phenol phenol activity was inhibited, resulting in a single phenol and two phenol enzyme activity decreased by 50%, used in cosmetics, which inhibit the formation of melanin.
