  • Publication number: 20230406987
    Abstract: A thermoplastic polyurethane is a reaction product obtained from components including (A) an aliphatic polyisocyanate, (B) an aliphatic polyol having at least one side chain, and (C) chain extenders. The aliphatic polyol (B) is a polycarbonate diol of formula (I): In formula (I), n is 4 to 40, and n+1 Rs are composed of a linear alkylene and an alkylene having at least one side chain so as to have the molar ratio of the linear alkylene to the alkylene having at least one side chain in the range of 0:100 to 95:5. The chain extender (C) is a combination of 1,4-butanediol with 1,3-propanediol, 1,5-pentanediol, 3-methyl-1,5-pentanediol, or ethylene glycol, and the amount of 1,4-butanediol is 50% by mass or more based on the total amount of the chain extenders (C). A resin composition containing the thermoplastic polyurethane and a corresponding molded product are also provided.
