The present invention provides a thermoplastic polyurethane composition
which comprises an ethylene-vinyl alcohol copolymer and/or a polyamide,
and a thermoplastic polyurethane, in which the retention of melt tension
thereof, when kept in a molten state at 220.degree. C. for 1 hour,
determined by the following equation (1), is not less than 10%. Retention
of melt tension (%)=[Melt tension after being kept in a molten state/Melt
tension before being kept in a molten state].times.100 (1)The
thermoplastic polyurethane composition of the present invention is
excellent in production stability of a molded article, and can provide a
molded article excellent in appearance because the progress of gelation
thereof is suppressed even in a molten state.
