An embodiment of a method includes generating a polymer solution using a polymerization process, the poly- merization process including preparing a solvent including at least N-formylmorpholine (NFM) or a combination of NFM with 3- methoxy N,N-dimethylpropanamide (MDP) as a cosolvent, mixing methylene diphenyl diisocyanate (MDI) and trimellitic anhydride N (TMA) with the solvent to generate the polymer solution, and diluting the polymer solution by adding an NFM:MDP solvent mix- ture or MDP into the generated polymer solution. The method further includes processing the diluted polymer solution to generate O polyamideimide polymer or a polyamide-amic acid resin polymer.
