The bio-polyol used in this study was castor oil (CO), which was procured from Alfa Aesar (Ward Hill, MA, USA). Lignin in the form of sulfonic acid calcium salt was purchased from Sigma-Aldrich (water soluble, contains 5 wt% Ca, impurities <5 wt%, St. Louis, MO, USA). The molecular weights of CO and lignin were determined by gel permeation chromatography (GPC) analysis as 1625 and 2029 g mol−1, respectively. Polytetramethylene ether glycol 2000 (PTMEG) was purchased from Korea PTG Co., Ltd (Ulsan, Republic of Korea). Isophorone diisocyanate (IPDI), N-methyldiethanolamine (MDEA), and diethanolamine (DEA) were procured from Samchun Chemical (Seoul, Republic of Korea). Dibutyltin didodecanoate (DBTDL) was purchased from Junsei Chemical (Tokyo, Japan). Methyl ethyl ketone (MEK) and acetic acid (AA) were obtained from Daejung Chemical (Busan, Republic of Korea). All materials were used as received without additional purification.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
