Provided is a polymer composition, wherein the polymer composition has a refractive index difference (B−A) of 0.04 or greater but 0.1 or less between a minimum refractive index A of the polymer composition in a temperature range of 5 degrees C. or higher but lower than 30 degrees C. and a maximum refractive index B of the polymer composition in a temperature range of 30 degrees C. or higher but lower than 50 degrees C.
提供了一种聚合物组合物,其中聚合物组合物在 5 摄氏度或更高但低于 30 摄氏度的温度范围内的最小折射率 A 与在 30 摄氏度或更高但低于 50 摄氏度的温度范围内的最大折射率 B 之间的折射率差 (B-A) 为 0.04 或更大但 0.1 或更小。
