New polyurethanes with high inherent viscosities of 1.74-2.10 dl/g in l,l,l,3,3,3-hexafluoro-2propanol were prepared by melt polycondensation of a 2,6-dioxydihexanol derivative of naphthalene, prepared from naphthalene-2,6-diol and 6-chloro-l-hexanol, with even alkylene diphenyl dicarbamates (n = 6,
A novel aqueous fluorine-containing polyurethane was prepared with a hydrophobic macromonomer of a perfluoroalkyl group. Two representative properties of the polyurethane, initial particle diameter dispersed in water and surface free energy of coating films, were investigated. The macromonomer was s
