Abstract: A stable solution of an aromatic polyamic acid of controlled molecular weight, of the type capable of being converted to polyimides, which undergoes relatively little change in viscosity or gelling over extended periods of time at room temperature. Such solution may be prepared by reacting impure aromatic dianhydride with aromatic diamine in a suitable solvent where the ratio of active aromatic diamines is approximately equimolar. Such solution may also be prepared by a two step process which comprises:Step I-Reacting a dianhydride of high purity (99+%) with a diamine in a molar ratio of about 0.95/1 dianhydride/diamine to yield a viscosity below about 10,000 cps, for example from about 2,000 to 6,000 at about a 10-15% solution.Step II-Then adding to I about 0.05 mole of a less pure dianhydride such as from about 97-99% pure dianhydride to yield a 10-15% solution of polyamic acid having a viscosity of about 10,000 cps.

Abstract: This invention relates to polymers prepared by reacting cyanuric acid and ethylene carbonate in situ to form the corresponding Tris(2-hydroxyethyl)isocyanurate-containing polymers including polyesters, polyester-imides, polyester-amide-imides, oil-modified derivatives thereof, etc. This invention also relates to such products employed as electrical insulation.

Abstract: This invention relates to (1) water soluble and/or dispersible compositions characterized by the presence of oil modified imidized polyesters; and to (1) which also contains curable resins. This invention also relates to a wide variety of uses for such compositions, such as electrical insulations, for example as in insulation varnishes, and related uses.

Abstract: This invention relates to imino dicarboxylic acids (IDA) of the general formulae ##STR1## where Z is a moiety, preferably aromatic, R is a moiety, preferably aliphatic, and to resins derived from such acids. Such resins, which may vary widely, are illustrated by polyesters, poly(ester-amides), poly(ester-imides), poly(ester-imide-amides), etc. In the preferred embodiment such resins contain tris (hydroxyethyl) isocyanurate. The preferred IDA, which is derived from trimellitic anhydride (TMA) and glycine, has the following idealized formula ##STR2## IS THE PREDOMINANT DICARBOXYLIC ACID EMPLOYED IN SUCH RESINS. This invention also relates to aromatic IDA where R is aryl as illustrated by IDA derived from aminobenzoic acid and resins prepared therefrom.

Abstract: This invention relates to a process of reformulating a solvent polyester-type resin, such as employed in electrical insulation, for example in wire enamels, to a solventless polyester-type wire resin of similar properties which is characterized by increasing the relative hydroxy-functionality of said polyester-type resin as compared to the hydroxy-functionality of a corresponding solvent-type wire resin.In the preferred embodiment the increased hydroxy-functionality, in whole or in part, is derived from the use of, or the increased content, of tris(2-hydroxyethyl) isocyanurate. The polyester-type wire enamels include polyesters and polyesters containing other groups such as polyester-amides, polyester-imides, polyester-amide-imides, etc. By doing this, resins having the desired properties as well as viscosities suitable for wire insulation can be made and applied in solventless systems.

Abstract: This invention relates to imino dicarboxylic acids (IDA) of the general formulae ##STR1## and ##STR2## where IS A MOIETY, PREFERABLY AROMATIC, R is a moiety, preferably aliphatic, and to resins derived from such acids.
