Abstract:
A thermoplastic polyurethane which comprises a segment (A) constituted of a high-molecular diol, a segment (B) constituted of at least one low-molecular diol selected between 1,4-bis(hydroxyethoxy)benzene and 1,3-propanediol, and a segment (C) constituted of a polyisocyanate, these segments being linearly bonded through a urethane bond, characterized in that the segment (B) accounts for 1 to 30 wt.% of the thermoplastic polyurethane.
