INVESTIGATION OF CONDENSATION TYPE ELASTOMERS

Abstract

The ultimate goal of the exploratory investigations described is the development of a rubber for special Air Force applications. High thermal stability (350 F or higher); resistance to aromatic fuels, synthetic ester base oils and hydraulic fluids; resistance to ozone and to weathering oxidation effects; resistance to acids, bases, and salts; resistance to abrasion; and satisfactory performance at -65 F or lower are major requirements for such an elastomer. To this end, a number of linear polyesters have been prepared from fluorine containing diols and various dicarboxylic acid chlorides, and their properties determined. Hexafluoropentylene adipate (made from adipyl chloride and 2,2,3,3,4,4-hexafluoropentanediol) is a rubber-like gum when of sufficiently high molecular weight, and this polyester has been crosslinked to evaluate the properties of the elastomer in the light of Air Force requirements.
