Claims
- 1. A composition comprising (A) at least one perfluoropolyether fluid of the formula:
- X--O--(C.sub.3 F.sub.6 O).sub.p --(CF.sub.2 O).sub.q --(C.sub.2 F.sub.4 O).sub.r --Y
- wherein the perfluoroalkyleneoxy groups are randomly distributed along the chain; p, q and r are each zero or a number from 1 to 100 inclusive, the sum of p, q and r being 6 to 200; X and Y are the same or different from each other and are perfluoroalkyl groups having 1 to 3 carbon atoms; and (B) from 0.1 to 50 parts by weight per 100 parts of perfluoropolyether fluid of a perfluoropolyether compound having at least one arylamide terminal group and being of the formula:
- A--O--(C.sub.3 F.sub.6 O).sub.P --(CF.sub.2 O).sub.Q --(C.sub.2 F.sub.4 O).sub.S --CF(Z)--CO--N(R)Ar
- wherein if two or more of the perfluoroalkyleneoxy groups, (C.sub.3 F.sub.6 O), (CF.sub.2 O) and C.sub.2 Fhd 4O) are simultaneously present in the chain, they are randomly distributed therealong; and wherein A is a perfluoroalkyl group having 1 to 3 carbon atoms or a --CF(Z)--CO--N(R)Ar group; P, Q and S are each zero but not simultaneously or a number ranging from 1 to 100 inclusive, the sum of P, Q and S being 3 to 200; Z is a fluorine atom or a CF.sub.3 group; Ar is an unsubstituted aryl group, or an aryl group which is mono-, di- or tri-substituted with a lower alkyl group, an alkylaryl group, phenyl or halogen, and R is a hydrogen atom, a lower alkyl group, an unsubstituted phenyl or phenyl group which may be bound to Ar either directly or through a sulfur atom.
- 2. A composition as claimed in claim 1, wherein the amount of perfluoropolyether compound is from 1 to 20 parts per 100 parts by weight of perfluoropolyether fluid.
