The present invention provides a polymer of Formula (4) or (5) as manufactured by polymerizing alkylmethacrylate of the formula (1) or its salt with 2-metacroxyethyl triammonium chloride of Formula (2) or vinyl monomer of phosphonium salt of the formula (3), and further provides a photochromic polymer matrix manufactured by blending the said polymer as the supporter with a known photochromic organic compound. Further, the present invention enables a glass or a mirror, of which the transmittance and/or the reflectance can be adjusted, to be manufactured by coating it with the said photochromic polymer matrix in a given thickness.
In the case of the glass manufactured by using the matrix of the present invention, it can be used in the field requiring adjustment the transmittance of light depending upon a weather condition, including a building or a car glass, a sunroof and the like. In the case of the mirror manufactured so, it can be applied to a rear-view mirror and a side view mirror for a vehicle and the like.
本发明提供一种式(4)或(5)的聚合物,其制造方法是将式(1)的烷基甲基丙烯酸酯或其盐与式(2)的2-甲氧基乙基三氯化铵或式(3)的膦盐乙烯基单体聚合,并进一步提供一种光致变色聚合物基体,其制造方法是将上述聚合物作为支持物与已知的光致变色有机化合物混合。此外,本发明通过在玻璃或镜子上涂覆一定厚度的上述光致变色聚合物基质,可以制造出透光率和/或反射率可调的玻璃或镜子。
使用本发明基质制造的玻璃可用于需要根据天气条件调节透光率的领域,包括建筑或汽车玻璃、天窗等。如此制造的镜子可用于汽车的后视镜和侧视镜等。
