| Abstract: | Linear polyurethane thermoplastics comprising furazan blocks soluble in organic solvents and having low melting points were obtained by nonequilibrium polycondensation of 3,4-bis(hydroxymethyl)furazan, butane-1,4-diol and 2,4-di-isocyanatotoluene. The thermal behavior of some copolymers was studied by DSC and TGA methods. |
