摘要： A thermoplastic polyurethan resin obtained by reacting (1) a polyol component with (2) an organic diisocyanate in a mole ratio, (1)/(2), of 0.8-1.3 : 0.5-1.2 in the presence, if desired, of a catalyst, said polyol component (1) comprising

(A) a linear polyester polyol and/or polyether polyol having hydroxyl groups at both ends and/or (B) a diol free from a tertiary hydroxyl group, and
(C) a low-molecular-weight polyol having at least one tertiary hydroxyl group (C-1), and/or a polyester polyol and/or polyether polyol having a molecular weight of 500 to 6,000 and containing hydroxyl groups at both ends and at least one tertiary hydroxyl group in the molecular chain (C-2) prepared from said low-molecular-weight polyol (C-1), the proportions of (A), (B) and (C) in said polyol component (1) being such that the ratio of (C) to the sum of (A), (B) and (C) is from 0.05 to 1.
