Claim Text:
1. A method comprising: reacting a filler with at least one thermally stable silane coupling agent selected from the group consisting of TAIC-silane, TMAIC-silane, TAC-silane and combinations thereof to covalently couple the silane to the filler, wherein reactivity of a vinyl group in the at least one thermally stable silane coupling agent is substantially the same as a vinyl group in a curing co-agent for a fluropolymer; reacting the covalently coupled silane-filler with the fluoropolymer to covalently couple the fluoropolymer to the covalently coupled silane-filler; and reacting the filler with the at least one thermally stable silane until substantially all surface sites of the filler comprise the silane coupling agent.
