US 10,619,000 B2  84  83  the reaction and low in its solution viscosity, it is good in  operability and is easily cast and coated. Thus, it can be used  for wide-range polyurethane applications.  Furthermore, since the polyurethane of the present inven› tion is derived from environmentally friendly plants while  keeping mechanical strengths such as abrasion resistance,  flexibility resistance, etc. as characteristics as conventional  polyester polyol-derived polyurethanes, it is expected that  the present invention is industrially extremely useful.
