Abstract
The present invention includes polymer interlayers that are used in multiple layer glazing panels. Interlayers of the present invention comprise a thermoplastic polymer, a plasticizer, a tungsten oxide agent, and a stabilizing agent that prevents the degradation of the tungsten oxide agent. Interlayers incorporating such components have improved ultraviolet light blocking character, and also maintain optical quality over time.
