Title:
POLYURETHANE RESIN
Document Type and Number:
WIPO Patent Application WO/2017/018320
Kind Code:
A1
Abstract:
Provided is a polyurethane resin comprising a modified olefin polymer that satisfies (1) through (3) below. (1) The limiting viscosity [η] as measured in tetralin solvent at 135°C is 0.01 to 2.5 dL/g. (2) The melting point (Tm-D) is either not observed or 0 to 100°C when defined as the peak top of a peak observed on the maximum-temperature side of the melting endothermic curve obtained by maintaining a sample for five minutes at -10°C under a nitrogen atmosphere and then raising the temperature by 10°C/minute using a differential scanning calorimeter (DSC). (3) The semi-crystallization time as measured using a differential scanning calorimeter (DSC) is three minutes or longer, or a crystallization peak as measured by a differential scanning calorimeter (DSC) is not observed.
