Process for producing bio-based polyether polyol, bio-based polyether polyol and bio-based polyurethane resin

The present invention relates to a method for producing a biopolyether polyol, which is a copolymerization reaction of tetrahydrofuran and 2-methyltetrahydrofuran in a monomer ratio (by mass) of 85/15 to 50/50, and the resulting polyether polyol of 100% plant origin having a number-average molecular...

Beschreibung
Zusammenfassung:	The present invention relates to a method for producing a biopolyether polyol, which is a copolymerization reaction of tetrahydrofuran and 2-methyltetrahydrofuran in a monomer ratio (by mass) of 85/15 to 50/50, and the resulting polyether polyol of 100% plant origin having a number-average molecular weight of 500-5000. In addition, a polyurethane resin, which is the product of a synthetic reaction having as the main reactants the above polyether polyol of 100% plant origin, a polyisocyanate compound, and a chain extender that reacts with isocyanate groups, has a change in storage modulus (E') in the low temperature range (0°C) with respect to normal temperature (20°C) of within 0-15%.
