ABSTRACT:
Polymeric compositions are provided in which perfluoropolyethers have been solubilized in non-fluorinated solvents by combining them with a solubilizing agent such as azotic conjugated compounds, and phosphorylated compounds. Typical of the perfluoropolyethers is ##STR1## Typical of the solubilizing agents is phosphorylated methacryloyloxyhydroxypropylisophthalate. The perfluoropolyether and the solubilizing agent are mixed to form a paste which is soluble in organic solvents such as methylethylketone. These compositions find utility as protective lubricant coatings for thin film magnetic recording media. They have the advantage that only one coating step is required in order to apply both the phosphorylated compound and the lubricating polyether. Recording media lubricated with these compositions have demonstrated excellent wear characteristics.
