(n is 10 on the average) containing a long chain fluorine› containing ether and having an average molecular weight of 2,000 on an ice bath with stirring. After completion of the addition, the mixture temperature was gradually increased to room temperature and stirring was carried out at room temperature for one hour. Then the reaction solution was subjected to separation with an acid and water to take out an oil layer. By concentration of the oil layer, 122 g of the following (2-pyrimidine )amide:

having a long chain fluorine-containing ether was obtained. According to $^{19}$F-NMR and lH-NMR analyses, it was confirmed that the obtained product was the above-men› tioned compound. This compound was insoluble in acetone and ethyl acetate and was a liquid at room temperature. Also as a result of TGA measurement in the air, T dlO was 310° C. and Tdso was 328° C.

(Effect as an Acid-removing Agent) 

[0256] Into 20 ml of 1 N aqueous solution of hydrochloric acid was poured 30 g of (2-pyrimidine )amide having a long chain fluorine-containing ether prepared in Example 18, followed by stirring at room temperature for 0.5 hour. During the stirring, the solution was separated into two layers. Also after completion of the stirring, the solution was separated into two layers, namely a lower layer of the (2-pyrimidine)amide having a long chain fluorine-contain› ing ether and an upper layer of the aqueous solution of hydrochloric acid. According to the investigation of acidity of this aqueous solution by using a pH test paper, the solution was changed from strong acid to neutral by treating with the amide. 

(Effect as an Acid-removing Agent) 

[0257] Into 20 ml of 1 N aqueous solution of acetic acid was poured 30 g of (2-pyrimidine )amide having a long chain fluorine-containing ether prepared in Example 18, followed by stirring at room temperature for 0.5 hour. During the stirring, the solution was separated into two layers. Also after completion of the stirring, the solution was separated into two layers, namely a lower layer of the (2-pyrimidine )a› mide having a long chain fluorine-containing ether and an upper layer of the aqueous solution of acetic acid. According to the investigation of acidity of this aqueous solution by using a pH test paper, the solution was changed from acid to neutral by treating with the amide.

deposition, and further thereon was formed an about 6 µm thick polystyrene layer by spin coating. On this layer was coated perfluoro(2, 5-bistrifluoromethy 1-3, 6-dioxadode› canoic acid (lubrication layer I) or a liquid composition prepared by mixing 10 g of perfluoro(2,5-bistrifluorom› ethyl-3,6-dioxadodecanoic acid)-(2-pyrimidine )amide and 10 g of perfluoro(2,5-bistrifluoromethyl-3,6-dioxadode› canoic acid (lubrication layer II) as a lubrication layer by spin coating. The coating amount was about 10 mg/m 2 . The coated film was set so that the lubrication layer was placed down, and was rubbed 100 times from below with a rod having a tip in the form of semi-cylindrical section of 5 cm longx3 cm diameter by applying a force of about 10 gf. A frictional force and remaining amount of metallic cobalt at the first rubbing and 100th rubbing are shown in Table 1. 

[0259] A change in the frictional force is evaluated by a speed of rubbing when rubbing with a given force, and the remaining amount of metallic cobalt is evaluated by observ› ing the surface of the coated layer with an optical micro› scope and checking an amount of falling cobalt (when adhesion is not good, cobalt powder falls). With respect to the evaluation criteria, when the rubbing speed does not change greatly, it is assumed to be O and when the rubbing speed decreases greatly, it is assumed to be x. Further when an amount of falling cobalt powder is small, it is assumed to be O and when an amount of falling cobalt powder is large, it is assumed to be x.

(Confirmation of Actuator Effect) 

[0260] A film of 0.2 mm thickxl cmx5 cm of NAFFION 117 (trademark of DuPont) was dipped in a 10- $^{2 }$N aqueous solution of AU(III)(phenanthrene)Cl3 at room temperature for 10 hours and then washed with pure water, and those procedures were repeated five times. Then the film was dipped in a 10-$^{3 }$N aqueous solution ofNa$_{2}$ SO$_{3 }$ at 50° C. for eight hours and thus a composite film of Au and NAFFION was obtained. Subsequently this composite film was dipped at room temperature for 12 hours in a 1 N aqueous solution of LiCI, 1 N aqueous solution of NH$_{4}$Cl or 1 N ethanol solution of the amide compound prepared in Example 1 to carry out ion exchanging. As a result, a NAFFION film in which a counter ion of sulfonic acid is Li+ ( counter cation I), a NAFFION film in which a counter ion of sulfonic acid is NH$_{4 }$+ ( counter cation II) and a NAFFION film in which a counter ion of sulfonic acid is a cation derived from the amide compound prepared in Example 1 ( counter cation III) were obtained. 

[0261] Next, a tip of each film was nipped with a Pt foil, an electric wire was connected to the Pt foil and the film was connected to a potentiostat (HA-501G available from Hokuto Denko Kabushiki Kaisha) through the wire. The film
