    摘要： Polyimides are prepared from acetylene substituted polyimide oligomers via an addition polymerization reaction which involves homopolymerization. These polymers exhibit low void content when cured and possess superior thermal stability characteristics and physical properties such as structural strength. One of their unique properties is their ability to be processed into useful articles at moderate pressures and temperatures.

    摘要： A thermosetting esterimide resin suitable for powder deposition atop an electrical conductor is formed by reacting a polyfunctional organotin compound with at least one polyhydric alcohol and a polycarboxylic acid or acid derivative in the presence of a catalyst to produce a polyester having tin atoms in the polymer backbone. A carboxy functional polyimide intermediate then is formed in conventional fashion, i.e., as the reaction product of a diamine and an aromatic carboxylic anhydride having at least one additional carboxylic acid group in the molecule, whereafter the tin containing polyester and the carboxy functional polyimide intermediate are slowly mixed at a maximum pot temperature of approximately 200*C to obtain a branched thermosetting esterimide resin containing tin atoms in the polymer backbone. When ground to a powder, e.g., 200-325 mesh, the esterimide polymer resin is suitable for electrostatic spray deposition atop an electrical conductor to form an electrically insulating coating thereon, with excellent corner coverage on rectangular wire, flexibility, thermal stability and varnish compatibility.

    摘要： A composition is disclosed of a dianhydride and a tetracarboxylic acid in the proportions of about 50 to about 70 mole % dianhydride to about 30 to about 50 mole % tetracarboxylic acid, a stoichiometric amount of an aromatic diisocyanate, and a solvent for the dianhydride, the tetracarboxylic acid, and the diisocyanate. A polyimide precursor is prepared by heating the composition at about 30* to 70*C until the evolution of carbon dioxide substantially ceases, and then at about 30* to about 100*C until its viscosity is about Q to about Z6 on the GardnerHoldt viscosity scale at 18% solids. The polyimide precursor can be spread on a substrate and cured to produce a polyimide film or coated on a wire and cured to produce a polyimide wire enamel.
