    摘要: Methods of making low density modified polyimide! polyimide-amide foams and the resulting compositions. An N-substituted aliphatic imide is prepared by reacting a suitable aromatic dianhydride with a suitable oxime. A polyimide forming material is prepared by dissolving the N-substituted aliphatic imide in an esterifying solvent, then adding a suitable aromatic diamine. This material is dried to a powder. A suitable hydrated compound which is stable up to at least about 100°C. is mixed with the powder. A foam is then produced by heating the material to reaction temperature for a period sufficient to produce a stable foam. The material melts, then spontaneously expands into a foam which becomes self supporting and cures to a resilient flexible foam. The addition of the hydrated compound is found to result in an exceptionally low density foam. Depending upon heating conditions, a polyimide, polyimide- amide or mixture thereof may be produced, resulting in foams having selectively variable physical properties.

    摘要: A method of making light weight flame resistant structures from bonded polyimide macroballoons. An aromatic tetracarboxylic acid dianhydride is reacted with a lactam to produce an N-substituted imide, which is then esterfied with a reactive solvent. At least one diamine is added. The resulting liquid is dried and the dry residue is reduced to an uniform powder having particles with diameters generally in the 0.5 to 10mm. range. The powder expands when heated to a temperature in the range of about 90 to 150°C for a suitable period. Closed cell "macroballoons" having average diameters between about 0.4 and 15mm. result. The macroballoons are bonded together with a very small amount of a suitable resin.

    摘要: @ A high temperature and flame resistant closed cell polyimide foam material and methods of making the foam. An aromatic tetracarboxylic acid dianhydride is reacted with an oxomine to produce an N-substituted imide, which is then esterified with a suitable alcohol. The resulting liquid is dried and the dry residue is reduced to a uniform powder having particles with diameters generally in the 0.5 to 10 mm range. The powder is preferably further dried, either before or after final size reduction, in a moderate vaccum at moderate temperature to remove any excess residual alcohol. The powder spontaneously expands to form a closed cell foam when heated to a temperature in the range of about 90 to 150°C for a suitable period. When the powder is expanded in a closed mold, a well consolidated, uniform, closed cell foam product results. When expanded in an unrestricted manner, closed cell "macroballoons" having average diameters between about 0.4 and 15 mm result. The closed cell foam produced has excellent flexibility and resistance to heat and flame, and does not shrink appreciably when exposed to flame.
