Abstract

In many electrostatographic applications, it is common practice today to employ fuser members made of Viton type elastomers which are based on a copolymer of vinylidene fluoride with hexafluoropropylene. Further, in some applications it is necessary to use charge control agents in the toner material such as, cetyl pyridinium chloride or other quarternary ammonium salts which have a tendency to react with the Viton, which has unsaturation previously formed via dehydrofluori-nation, to produce increased crosslinking, and thereby hardening and/or a reaction product with the cetyl pyridinium chloride; W e propose the saturation of the double bonds in the Viton to prevent further crosslinking and thereby hardening and other deleterious quaternary ammonium salt reactions. In particular, we envision the addition of a silanic hydrogen compound to saturate the double bond. Typical materials envisioned include, polymethylhydrosiloxane which will covalently bond to the Viton via the double bonds formed due to hydrofluorination. In addition, the covalent bond of the siloxane compound on the surface of the Viton will afford good release characteristics associated with the silicone moiety.
