Title:
THERMOPLASTIC POLYURETHANE RESIN
Document Type and Number:
WIPO Patent Application WO/2010/098027
Kind Code:
A1
Abstract:
Disclosed is a thermoplastic urethane resin of superior hydrolysis resistance and excellent melt characteristics. The thermoplastic polyurethane resin (U) is a polyurethane resin (U) made by reacting a polyester diol (P) and a diisocyanate (S), and is characterized in that the diisocyanate (S) contains an unmodified diisocyanate (S0) and a carbodiimide-modified 4,4'-dicyclohexylmethane diisocyanate (H), the mole ratio of (S0) to (H) is 40:1 to 1000:1, and the ratio of the peak height of the uretone imine bonds (near 1715 cm-1) to the peak height of the methylene C-H bonds (near 2922 cm-1) in (H), from infrared spectroscopic analysis, is not more than 1.5.
