SYNTHETIC POLYMERS HAVING IMPROVED PHOTOSTABILITY THROUGH THE INCORPORATION OF INORGANIC PHOSPHORS

Described herein are methods for improving the color stability of a synthetic polymer composition by incorporating one or more inorganic phosphor dopants into the synthetic polymer. The inorganic phosphor dopants absorb UV light and emit the UV light as down-converted visible light, thereby producin...

Beschreibung
Zusammenfassung:	Described herein are methods for improving the color stability of a synthetic polymer composition by incorporating one or more inorganic phosphor dopants into the synthetic polymer. The inorganic phosphor dopants absorb UV light and emit the UV light as down-converted visible light, thereby producing a brighter appearance for the synthetic polymer composition. Methods for preparing the synthetic polymer compositions having improved color stability are additionally described.
