Perfluoropolyether compounds , manufacturing method thereof, a lubricant containing the compounds , and magnetic disks

摘要

PROBLEM TO BE SOLVED: To provide a compound (lubricant) which is stable under heat, and shows improved flow property and adsorptivity on a disc surface compared to conventional terminal-modified compounds, by introducing a new terminal functional group into a perfluoropolyether having a hydroxy group.;SOLUTION: The lubricant contains a perfluoropolyether compound having a group represented by formula (2) (wherein R is hydrogen, 1-10C alkyl or alkoxy and n is 1 or 2) within the molecule.;COPYRIGHT: (C)2010,JPO&INPIT
