てしまう。Comparative Example 108 g of 1,3-bis(2-oxazolinyl-2)benzene and 73 g of adipic acid were thoroughly mixed in a mortar and placed in a mold at 200°C. After the internal temperature exceeded 180°C, the temperature of the mold was kept at 200°C for 20 minutes, and then allowed to cool, allowing the temperature to drop to around room temperature before being removed, yielding a transparent cured product. This cured product is 50 to 60
It softens at temperatures above 100°C and loses its shape if pressed at temperatures above 100°C.

It melted and became liquid after 2 minutes, and gelled after 14 minutes. After that, the temperature was kept as it was for 10 minutes, then the temperature was raised to 190°C, kept for 10 minutes, and then allowed to cool to obtain a cured product. This cured product had no melting point and had a decomposition temperature of about 280°C.
