Embodiments generally relate to the preparation of polyamidoimide resins using N-formyl morpholine: 3-methoxy N, N-dimethylpropanamide. Embodiments of the method include forming a polymer solution using a polymerization method, wherein the polymerization method is a solvent comprising at least N-formyl morpholine (NFM), or 3-methoxy as a co-solvent with one set of NFM Preparing a combination of N, N-dimethylpropanamide (MDP), mixing methylene diphenyl diisocyanate (MDI) and trimellitic anhydride (TMA) with the solvent to form a polymer solution, the polymer Diluting the solution by adding the NFM: MDP solvent mixture or the MDP to the generated polymer solution. The method further comprises the step of treating the diluted polymer solution to form a polyamideimide polymer or a polyamide-amic acid resin polymer. |
