example 1
[0083]To 100 parts of a fluorinated polyether polymer of the following formula (3) (viscosity 4,400 cs, number average molecular weight 16,500, vinyl content 0.013 mol / 100 g) was added 800 parts of spherical atomized silver (mean particle size 0.2 μm). Then 2.7 parts of a fluorinated hydrogenated siloxane of the following formula (4) as a crosslinking agent, 0.5 part of a 50% toluene solution of ethynyl cyclohexanol, 1.0 part of a tackifier of the following formula (5), and 10 parts of m-xylene hexafluoride were added. After the ingredients were uniformly agitated, 0.2 part of a 1,3-divinyl-1,1,3,3-tetramethydisiloxane complex of chloroplatinic acid (platinum concentration 1.0 wt %) was added to the mixture and thoroughly mixed therewith. The mixture was cast on a Teflon-coated support. After the solvent volatilized off, the coating was heat cured at 120° C. for one hour into a sheet of about 1 mm thick. The sheet was measured for volume resistivity, finding a value of 3×10−5 Ω-cm.

[0085]To 100 parts of a fluorinated polyether polymer of the following formula (6) (viscosity 12,200 cs, number average molecular weight 16,000, vinyl content 0.013 mol / 100 g) were added 46.3 parts of a compound of the following formula (7) as a crosslinking agent, 1.0 part of a compound of the following formula (8) as a tackifier, 800 parts of dimethylsiloxane-treated, flake-shaped silver particles prepared by the procedure described below, 0.5 part of a 50% toluene solution of ethynyl cyclohexanol, and 1.0 part of a tackifier of above formula (5). After the ingredients were uniformly agitated, 0.2 part of a 1,3-divinyl-1,1,3,3-tetramethydisiloxane complex of chloroplatinic acid (platinum concentration 1.0 wt %) was added to the mixture and thoroughly mixed therewith. The mixture was cast on a Teflon-coated support and heat cured at 120° C. for one hour into a sheet of about 1 mm thick. The sheet was measured for volume resistivity, finding a value of 1×10−5 Ω-cm.
