    摘要： Aspects described herein generally relate to methods of making a phosphono paraffin comprising forming a reaction mixture by mixing a haloparaffin, a phosphite, and sodium iodide. Methods comprise heating the reaction mixture to form the phosphono paraffin. Aspects described herein further relate to a phosphono paraffin represented by formula (I): wherein each instance of R1 is independently —H or wherein each instance of R2 and R3 is independently linear or branched C1-20 alkyl, C1-20 cycloalkyl, or aryl; the number of instances where R1 is of formula (I) is between about 2 and about 8; and n is an integer between 4 and 22.

    摘要： A lubricant for a magnetic disk that is excellent in heat resistance and is suitably used in a magnetic disk to be mounted on a magnetic recording device of a thermally assisted magnetic recording system and a magnetic disk provided with a lubricant layer containing this lubricant. The lubricant for a magnetic disk contains a compound where perfluoropolyether groups each having a perfluoropolyether main chain in its structure and a phosphazene ring at an end are linked to each other through a linking group. The linking group is an aliphatic group or a phosphazene ring. In a magnetic disk having at least a magnetic recording layer, a protective layer, and a lubricant layer on a substrate, the lubricant layer contains the lubricant for a magnetic disk.
