The copoly(urethane-imide) chosen as the object of study was obtained according to the synthesis method outlined in our initial studies [39 (link),40 (link),41 (link),42 (link),43 (link),44 (link),45 (link)]. At that, pyromellitic anhydride with a melting point (T_m)~283–286 °C, Sigma-Aldrich Co., LLC, Burlington, MA, USA; polycaprolactone with molecular weight Mn = 2000, Sigma-Aldrich Co. LLC with melting point (T_m)~50 °C; 2,4- toluene diisocyanate with melting point (T_m)~20–22 °C, Sigma-Aldrich Co., LLC; 4,4′-diaminodiphenyl ether with melting point (T_m)~188–192 °C, Sigma-Aldrich Co., LLC. were used as monomers. N,N-dimethylacetamide, Vecton Co., LLC, Russia, Saint Petersburg was used as a solvent.

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.
