PROBLEM TO BE SOLVED: To obtain a lubricant compsn. which has excellent lubricating properties, exhibits stable travelling properties, abrasion resistance, durability, etc., and is excellent in solubility in general-purpose solvents by using a combination of a perfluoropolyalkyl ether having both molecular ends hydroxylated and a long-chain alkylamine. SOLUTION: This compsn. comprises a perfluoropolyalkyl ether having both molecular ends hydroxylated as represented by formula I (wherein Rf is a perfluoropolyether group) and a long-chain alkylamine represented by formula II (wherein R is an alkyl or aralkyl). Pref. the ether has a mol.wt. of 1,000 or lower. The number of carbon atoms of the amine is pref. 6 or higher. The mixing ratio of the amine to the ether is pref. 0.1-0.5. |
