| 摘要 |
Novel polyimide prepolymers are produced by reacting an unsaturated dicarboxylic acid imido acylchloride with a difunctional amine to produce the corresponding acid amide. Condensation of said reactants is preferably effected in solution in a low boiling solvent. The resulting prepolymer is hardened and completely polymerized by heating, preferably between about 80 DEG C. and about 400 DEG C., to yield a cross-linked, substantially infusible and insoluble polyimide resin and articles made therefrom.
