Abstract
The present invention is directed to electrochromic electrolyte polymer blends. These blends comprise an amorphous polymer and an electrochromophore component. The electrochromophore component comprises a polyalkylene polymer copolymerized with an electrochromic moiety. The blends can be used to make elastomeric films and coatings that can be used in laminates, which can be used to form manufactured articles such as architectural and vehicular glazing, eyewear, displays and signage.
