THERMOPLASTIC POLYURETHANE RESIN, THERMOPLASTIC POLYURETHANE RESIN COMPOSITION, MOISTURE-PERMEABLE RESIN MOLDED ARTICLE MADE FROM THERMOPLASTIC POLYURETHANE RESIN AND METHOD FOR PRODUCING THERMOPLASTIC POLYURETHANE RESIN

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic polyurethane resin which delays aggregation of a polyurethane resin being a component of a molded article such as a film and a sheet made from a polyurethane resin while keeping high moisture permeability, effectively suppresses occurrence of dots causing poor appearance of a molded article, has good workability, and there is consideration taken about contamination caused by an organic solvent in production of a conventional moisture permeable film made from a polyurethane resin.;SOLUTION: A thermoplastic resin is a reactant of a polyol component containing a polyethylene glycol and tetrahydrofuran-neopentyl glycol copolymer being a raw material for moisture-permeable resin molded article, and an isocyanate component.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
