[PROBLEMS] To provide a polymer material synthesized from a raw material derived from a natural molecule, which has a performance capable of replacing a polyimide or polyamide synthesized from a petroleum raw material. [MEANS FOR SOLVING PROBLEMS] A polymer material comprising a polymer raw material comprising a dimer of a 4-aminocinnamic acid, which is a natural molecule, or a dimer of a 4-aminocinnamic acid derivative, wherein a carboxyl group is protected with an alkyl chain. It is. FIG. 5 shows TGA curves of polyamic acid (PAA-1) and polyimide (PI-1) according to the present invention. Selection Figure 5 |
