    • PURPOSE: A thermoplastic polyurethane resin, its preparation method and a polyurethane adhesive are provided, which thermoplastic polyurethane resin is improved in adhesive strength and is useful to the adhesion of a polymer film and a metal material. CONSTITUTION: The thermoplastic polyurethane resin comprises a polyol containing an organic diisocyanate and an active oxygen, and optionally a polyhydric alcohol, wherein the polyol is the polyol which is modified by an acid anhydride and an epoxy-containing silane compound. Preferably the acid anhydride is selected from the group consisting of maleic anhydride, 2-methylpropionic anhydride, itaconic anhydride, citraconic anhydride, trimellitic anhydride, pyromellitic anhydride, phthalic anhydride and their mixtures; and the epoxy-containing silane compound is selected from the group consisting of γ -glycidoxypropyltrimethoxysilane, γ-glycidoxypropylmethyldithoxysilane, β -(3,4-epoxycyclohexyl)ethyltrimethoxysilane and their mixtures. The polyurethane adhesive comprises the thermoplastic polyurethane resin and polyisocyanate.
