Abstract : The invention relates to improved lubricants and more particularly concerns grease compositions which are chemically and physically stable over wide temperature ranges for extended periods. Briefly, the authors have discovered new grease compositions especially useful to the military wherein trimethylolpropane esters of certain fatty acids are thickened with a perfluoro polymer. It was found that trimethylolpropane esters of n-heptoic and n-nonanoic acid in any proportion of 10 to 90 weight percent of either may be thickened with tetrafluoroethylene polymer having a molecular weight of about 10,000-50,000 to produce a stable, grease-type lubricant for military applications, among others.
