    摘要: A polyurethane suitable for producing leatherlike sheets, which is prepared by the reaction among a diol (A) having a tertiary amino group, a polymer diol (B) having the number-average molecular weight of 500 to 3,000 and selected from the group consisting of polyesters, polycarbonates, polylactones and polyethers, and an organic diisocyanate (C1) each in such an amount that the equivalent ratio of the NCO groups to the OH groups will range from 0.5 to 0.99 to thereby prepare an intermediate diol (D) substantially terminated by OH groups, followed by the reaction among the diol (D), a low-molecular-weight diol (E) and diphenylmethane 4,4'-diisocyanate (C2); and a leatherlike sheet composed of the polyurethane and a fibrous base material, which is soft to the touch, excellent in durability, and dyeable with acid dyes.
