    摘要： A lubricant composition comprising a first fluoropolyether and a second fluoropolyether having nitrogen containing end-group exhibits improved resistance to acid and thermal decomposition. Embodiments include a lubricant composition containing a perfluorinate polyalkylether admixed with a perfluorinated polyalkylether having amide terminal groups and applying the composition to the surface of a magnetic recording medium to form a homogeneous lubricant topcoat thereon.

    摘要： A material, preferably a magnetic data storage disc, includes a carbon layer covering at least a portion of a magnetic substrate and a crosslinked fluoropolymer layers covering at least-a portion of the carbon layer. The crosslinked polymer layer has a thickness less than about 40 angstroms, and the carbon layer has a thickness less than about 100 angstroms. Preferred fluoropolymers include, for example, perfluoropolyethers. In some embodiments, the crosslinked fluoropolymer layer has a thickness at one point on the carbon layer greater than the thickness crosslinked fluoropolymer layer at another point on the carbon layer. The crosslinking generally is performed by irradiating the lubricant material on the carbon layer.

    摘要： A fluoropolyalkylether is prepared under mild reaction condictions by combining a fluoropolyalkylether substituted with one or more ester end-groups with an amine. Embodiments include combining: (i) a fluoropolyalkylether substituted with one or more ester end-groups having the formula: Rf—(COOR′)q with (ii) an amine having the formula: HNR1R2 and (iii) a solvent comprising a hydrofluorocarbon or a hydrofluoroether together with a lower alcohol at a temperature of from about 15° C. to about 30° C. to form the fluoropolyalkylether amide, where Rf is a perfluoropolyether, R′ is a lower alkyl group, q is 1-4; R1 is H and R2 is a C2-C4 or a C2-C4 substituted with at least one hydroxyl group.
