Polyamide-imides are either thermosetting or thermoplastic, amorphous polymers that have exceptional mechanical, thermal and chemical resistant properties. Polyamide-imides are used extensively as wire coatings in making magnet wire. They are prepared from isocyanates and TMA (trimellic acid-anhydride) in N-methyl-2-pyrrolidone (NMP). A prominent distributor of polyamide-imides is Solvay Specialty Polymers, which uses the trademark Torlon. Witryna1 maj 2013 · The imidized copolymer was essentially water-insoluble, but after ring-closure the polymer samples were again soluble in ethyl acetate, the solvent in which the ring-opening reaction was carried out. ...
