Abstract
A method for producing thermoplastic polyurethane by using macropolyol of a high melting point, a chain extender of a high melting point and polyisocyanate slow to react as well as a reduced amount of catalyst for producing thermoplastic polyurethane, by which there are provided less gelled substance and burnt deposits as well as less reduction in property and deterioration-with-time; an apparatus for use in the method for producing thermoplastic polyurethane; and the thermoplastic polyurethane obtained by the method for producing thermoplastic polyurethane. After polyisocyanate and macropolyol are mixed by a high-speed agitator, chain extender is blended in the mixture thus obtained simultaneously or at a later stage, to prepare reaction material, first. Then, the reaction material is allowed to react while passing through a plurality of static mixers in a static mixer part.
