One embodiment of the present invention relates to a method for producing a polyimide resin, comprising the steps of: (a) reacting at least one of a diene monomer and a compound represented by the following Chemical Formulas 1 to 3 in the presence of a catalyst; And (b) further polymerizing a diene monomer to the product of step (a). The present invention also provides a process for producing a functional gossypolyadiene. ≪ Formula 1 > (2) (3) Wherein R 1 to R 3 are each a C 1 to C 20 alkyl group, an aryl group, an alkoxy group, -NR'R '', -SiR'R '' R '''',R''' are each a C 1 to an alkyl group, an aryl group, an alkoxy group or a hydrogen of the C 20, Z 1 is silicon, tin, nitrogen, oxygen, sulfur, phosphorus, carbon or hydrogen, a 1 is C 1 To C 20 alkylene or arylene group, and n is an integer of 1 to 20. |
