ABSTRACT:
Flexible magnetic recording tape is lubricated by a thin coating of a fluorinated telechelic polyether polymer having at least one polar group such as --CONHCH.sub.2 CH.sub.2 OH, --COOCH.sub.3, --CH.sub.2 OH, and --COCF.sub.3. This is believed to provide for the first time reliably effective lubrication at 40.degree. C. and 80% relative humidity.
