Title:
THERMOPLASTIC URETHANE RESIN
Document Type and Number:
WIPO Patent Application WO/2011/070751
Kind Code:
A1
Abstract:
For the purpose of providing a material for slush molding which has excellent low-temperature meltability and which can provide a molded product with excellent tensile strength and elongation, a thermoplastic urethane resin (D) for thermal molding is disclosed.
The thermoplastic urethane resin (D) is a thermoplastic urethane resin obtained by reacting a high-molecular diol (A) with a diisocyanate (B), said high-molecular diol (A) comprising a polyester diol (A1) which has a glass transition temperature of 0 to 70°C and a high-molecular diol (A2) which has a solubility parameter lower than that of the polyester diol (A1) by 1.2 to 3.0 and which has a glass transition temperature of -40 to -75°C.
