Several polyformals of novel fluorodiols and fluoronitrodiols provided by Fluorochem, Inc. were prepared. The previously prepared polyformal of tetranitrodioxatridecanediol was obtained with a molecular weight up to 10, 000. This soft block has a TG of -11 C. The synthesis of polyazidoacetals as potential soft blocks was initiated. The first example successfully synthesized was the polyazidoacetal of 1,6-hexanediol. New monofunctional, isocyanate terminated hard blocks with estimated melting points of 50-100C were synthesized, including the 11 adduct of docosanol and toluene diisocyanate TDI.
