Example 2

60 g of styrene maleic anhydride (SMA, commercially available from Polyscope, weight average molecular weight (Mw):9000) was put into 80 g of dimethylacetamide (DMAc) to be pre-dissolved. 22.33 g of furfurylamine (FA, commercially available from Aldrich) was then added into DMAc and SMA, and then heated to 100° C.˜160° C. and stirred to react. After completing the reaction, the temperature was cooled to room temperature to obtain an oligomer having a structure represented by Formula (I-1). Subsequently, the physical properties of the oligomer were measured, as shown in Table 1.

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.
