    Abstract: A modified completely imidized aromatic polyamide-imide resin which can be applied from conventional phenolic solvents such as cresylic acid, phenols, cresols and the like. The method of the invention includes reacting an aromatic diisocyanate and an aromatic tricarboxylic acid anhydride in an aprotic solvent, modifying the reaction product with an aliphatic dicarboxylic acid, and diluting the same to an appropriate degree with a solvent. Solutions of the resin having relatively low viscosity and a relatively high resin content can also be made by the method of the invention. The modified polyamide-imide resin of the invention has thermal stability and toughness approaching non-modified aromatic polyamide-imide resins and are fully useful as such resins as insulation materials in the electrical industry.

    Abstract translation: 一种改性的完全酰亚胺化的芳族聚酰胺酰亚胺树脂，其可以用常规的酚类溶剂如甲酚酸，酚类，甲酚等来使用。 本发明的方法包括使芳族二异氰酸酯和芳族三羧酸酐在非质子溶剂中反应，用脂族二羧酸改性反应产物，并用溶剂将其稀释至适当的程度。 通过本发明的方法也可以制备具有较低粘度和较高树脂含量的树脂的溶液。 本发明的改性聚酰胺酰亚胺树脂具有接近非改性芳族聚酰胺 - 酰亚胺树脂的热稳定性和韧性，并且作为电气工业中的绝缘材料的树脂是完全有用的。

    Abstract: GROUPS WHERE R IS ANY ALIPHATIC OR AROMATIC ORGANIC RADICAL AND A THERMOPLASTIC RESIN HAVING A PLURALITY OF HYDROXYL GROUPS. THIS RESINOUS PRODUCT IS SOLUBLE IN A SOLVENT TO THE EXTENT THAT ARTICLE MAY BE COATED OR IMPREGNATED WITH THE RESINOUS COMPOSITION BY CONVENTIONAL DIPPING OR WIPING FOLLOWED BY SOLVENT EVAPORATION. ARTICLES COATED WITH THE RESINOUS PRODUCT CAN BE BONDED TOGETHER BY SOFTENING THE PRODUCT EITHER BY HEATING THE RESINOUS COATING TO TEMPERATURES ABOVE ITS SOFTENING POINT OR BY APPLYING SELECTIVE SOLVENTS TO THE RESINOUS COATING. THE SIGNIFICANT FEATURE OF THE NEW RESINOUS PRODUCT IS THAT THE RESINOUS PRODUCT CAN THEN BE THERMOSET, IF DESIRED. IN SPECIFIC APPLICATIONS, THE NEW RESINOUS PRODUCT CAN BE USED AS A MAGNET WIRE ENAMEL AND A CEMENT FOR BONDING COATED ARTICLES INTO VARIOUS SELF-SUPPORTING AND INTEGRAL STRUCTURES FOR EXAMPLE COILS MADE OF MAGNET WIRE, AND OTHER FIXED FORMS MADE OF FIBROUS MATERIALS SUCH AS PAPER OR CLOTH MATERIALS INCLUDING TEXTILES AND NONWOVEN MATERIALS IMPREGNATED WITH THE RESINOUS PRODUCT OF THIS INVENTION OR FURTHER AS AN ADHESIVE THAT CAN BE THERMOSET BY THE METHOD OF THE INVENTION. THE METHOD OF THE INVENTION, IN THE SPECIFIC EMBODIMENT RELATING TO MAGNET WIRE, INCLUDES THE STEPS OF COMBINING THE RESIN AND COMPOUND ABOVE-MENTIONED TO FORM A RESINOUS PRODUCT, PREPARING A SOLUTION OF THE RESINOUS PRODUCT, COATING A CONDUCTOR WITH THE RESINOUS PRODUCT IN A CONVENTIONAL MANNER WHICH INCLUDES THE BAKING OF THE COATED CONDUCTOR TO REMOVE THE SOLVENT THEREFROM, FORMING A COIL OF THE MAGNET WIRE COATED WITH THE PRODUCT, AND BONDING ADJACENT PORTIONS OF MAGNET WIRE TOGETHER TO FORM A BONDED COIL PRODUCT. THIS LATTER STEP CAN BE PERFORMED BY USING ADDITIONAL SOLVENT OR BY HEATING THE COIL IN A SELECTED MANNER WHICH MAY RESULT IN THE RESINOUS PRODUCT EITHER REMAINING THERMOPLASTIC OR BECOMING THERMOSET, AS DESIRED.

    Abstract: A METHOD OF MAKING ESSENTIALLY TOTALLY IMIDIZED POLYAMIDE-IMIDE RESINS, AROMATIC AMIDES, AND OTHER AROMATIC POLYAMIDE RESINS WHICH CAN BE APPLIED TO ARTICLES WITHOUT THE RESINS UNDERGOING SUBSTANTIAL CHEMICAL CHANGE AS THE RESINS ARE BEING APPLIED, AND INTERMEDIATES FORMED DURING THE PERFORMANCE OF THE METHOD. SPECIFIC POLYAMIDE-IMIDE RESINS WHICH CAN BE MADE IN ACCORDANCE WITH THE METHOD OF THE INVENTION ARE THOSE DERIVED FROM TRICARBOXYLIC ACIDS OR ANHYDRIDES THEREOF, SUCH AS TRIMELLITIC ACID OR TRIMELLITIC ACID ANHYDRIDE, AND A DIISOCYANATE, SUCH AS P,P''-DIPHENYL METHANE DIISOCYANATE. THE METHOD COMPRISES AN INITIAL REACTION UNDER MILD CONDITIONS AND A SUBSEQUENT REACTION UNDER MORE SEVERE CONDITIONS.
