Attenuation of polymer substrate degradation due to ultraviolet radiation |
摘要 |
Improved methods and polymer compositions are provided whereby ultraviolet radiation degradation of substrates formed of the compositions is attenuated. In accordance with the invention, ultraviolet scattering and absorbing particles having a particle size in the range of from about 0.001 micrometer to about 0.20 micrometer in diameter are dispersed in at least a surface layer of a polymer substrate.
