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.

Thereto was slowly  added dropwise 120 g of the following acid fluoride:  (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.

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.  (Confirmation of Lubricity)  [0258]  On a polystyrene film of about 100 µm thickx3  cmxl0 cm was coated metallic cobalt by vacuum vapor  (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.
