METHOD FOR PRODUCING A BIOPOLYETHER POLYOL, BIOPOLYETHER POLYOL, AND BIOPOLYURETHANE 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 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%.

Supercritical carbon dioxide morphologically modified acid-based halloysite catalyst
The efficient production of poly(tetramethylene ether) diacetate [PTMEA] or other diesters, from tetrahydrofuran [THF] is obtained utilizing an acid-based catalyst that is based on a morphologically reconfigured and Bronsted acidity enhanced halloysite derived from a preparation method of using naturally occurring halloysites. More specifically, the method relates to morphological modification of the internal pore structure of halloysites via supercritical carbon dioxide treatment directly applied onto the raw halloysite minerals, that yields highly synergistic and reproducible results of elimination of inaccessible and detrimental extra-small pores. PTMEA is readily converted to poly(tetramethylene ether) glycol (PTMEG) by a transesterification reaction
