    摘要: The products of the invention are acetylene end-capped polyimide oligomers prepared from a dianhydride of an aromatic tetracarboxylic such as 3, 3', 4, 4'-benzophenonetetracarboxylic acid, an aromatic triamine, and a propargyl ester of an amino-substituted aromatic acid such as aminobenzoic acid. The structure of the polyimide oligomers is shown in FIG. 3.

    摘要: A group of heat curable resins are provided which have good physical properties, which properties are retained to a surprising degree after prolonged exposure to temperatures as high as 300.degree. C. The products are acetylene end-capped esterimides having the structure: ##STR1## where R is an arylene group or a group having the structure: ##STR2## where X is ##STR3## R.sub.1 is an alkyl group containing 1 or 2 carbon atoms and R.sub.2 is hydrogen or an alkyl group containing 1 or 2 carbon atoms; and where R' is a phenylene group.
