Abstract:

An object of this invention is to provide a new curable polyfluoro prepolymer. Another object of this invention is to provide a new curable polyfluoro prepolymer which is miscible with conventional plasticizers, curing agents, and other polymers. Other objects of this invention are to provide a curable polyfluoro prepolymer which may be used to provide a binder in castable or extrudable composites and to provide an energetic, curable prepolymer for use in a binder in castable or extrudable explosive or propellant compositions. These and other objects of this invention are accomplished by providing 2,4,4,5,5,6,6-heptafluoro-2-trifluoromethyl-3-oxaheptane-1,7-diol polyformal, HOCH2CF2CF2CF2OCFCF3CH2OC-H2OCH2CF2CF2CF2OCFCF3CH20nH, wherein n 1, which is prepared by reacting 2,4,4,5,5,6,6-heptafluoro-2-trifluoromethyl-3-oxaheptane-1,7-diol with formaldehyde in 80-90 sulfuric acid.
