Disclosed herein are functionalized polymers comprising ethylene and substituted ethylene segments, which have been crosslinked using a multifunctional thiol to enhance their crosslinking ability. These functionalized polymers are useful as film forming resins in cathodic electrocoating compositions. Also disclosed herein are aqueous dispersion compositions comprising the functionalized polymers and a process for coating various electrically conductive substrates.

Cathodic electrocoating compositions

Polyimide resin compositions that contain an aromatic polyimide, graphite, and acicular titanium dioxide are found to exhibit high thermal oxidative stability. Such compositions are especially useful in molded articles that are exposed to high temperatures, such as bushings, bearings, and seal rings that are used in aerospace, transportation, and materials handling applications.

Polyimide resins for high temperature applications

Disclosed herein are functionalized polymers comprising ethylene and substituted ethylene segments, which have been modified by epoxidation to enhance their crosslinking ability. These functionalized polymers are useful as film forming resins in cathodic electrocoating compositions. Also disclosed herein are aqueous dispersion compositions comprising the functionalized polymers and a process for coating various electrically conductive substrates.

Amorphous polymers with chromogenic pendant groups are provided. The amorphous polymers can be used to make elastomeric films and coatings that can be incorporated into laminates and used to make articles such as architectural and vehicular glazing, and in applications such as eyewear, displays and signage.

Amorphous polymers with pendant chromogenic groups

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.
