Investigation of the synthesis of polyformals from nitro- and fluorodiols was continued. Factors affecting the molecular weight distribution of hexafluoropentanediol and 2-tri-fluoromethyl-3-oxaheptafluoroheptanediol polyformals were determined. In the polycondensation of 4,4-dinitroheptanediol with formaldehyde, monomer concentration, solvent, type of Lewis acid catalyst, and reaction temperature were the important parameters affecting polymer yield and properties. In the polycondensation of formaldehyde with two nitramine
