Claim 3:
4. A manufacturing method of a thermosetting polyimide resin, wherein a chemical structure of the thermosetting polyimide resin is shown in Formula (1):, where P is a C36 divalent hydrocarbon group having an aliphatic side chain;
X and Y are, R1 and R2 are F or CH3;
R3 is, or, and
n is an integer from 1 to 5000;
the manufacturing method of the thermosetting polyimide resin comprising:
a procedure A of performing a dehydration reaction on C36 dimer diamine and fluorene dianhydride in a mixed solvent of a polar solvent and a low-polarity solvent to obtain a first solution containing an amine-terminated polyimide resin;
a procedure B of adding allylsuccinic anhydride to the first solution to perform the dehydration reaction on the allylsuccinic anhydride and the amine-terminated polyimide resin to obtain a second solution containing an allyl-terminated polyimide resin; and
a procedure C of removing any unreacted material, water-soluble substance, and water from the second solution to obtain the allyl-terminated polyimide resin.
