摘要： A process for PAI-based coating compositions. An embodiment of a method includes manufacturing a coating composition, the manufacturing of the coating composition including mixing a first solvent, the first being solvent being N-formyl morpholine (NFM), with a second solvent to form a first solution; dissolving polyamideimide or polyamide amic acid resin polymer (PAI) in the first solution; precipitating a PAI compound from a mixture of MEK and the first solution; and dissolving the PAI compound in a second solution to generate a coating solution.

摘要： A process for preparing polymer. An embodiment of a method includes generating a resin solution including a first reaction solvent and a polymer resin dissolved therein; deploying the resin solution into a precipitation solvent contained in a chamber of a reaction vessel, wherein deploying the resin solution includes generating droplets of the resin solution; disturbing a resulting mixture of the resin solution and the precipitation solvent, wherein the mixture produces a precipitate; and generating a polymer powder from the mixture, including isolating the precipitate from a remaining portion of the mixture, and drying the isolated precipitate.

摘要： Embodiments generally relate to preparation of polyamide-imide resins using N-Formyl Morpholine:3-Methoxy N,N-Dimethylpropanamide. An embodiment of a method includes generating a polymer solution using a polymerization process, the polymerization 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 (TMA) with the solvent to generate the polymer solution, and diluting the polymer solution by adding an NFM:MDP solvent mixture or MDP into the generated polymer solution. The method further includes processing the diluted polymer solution to generate polyamideimide polymer or a polyamide-amic acid resin polymer.
