Abstract
The present invention relates to novel imide oligomer compositions, polyimides formed therefrom, and methods for making and using the same. In particular, the invention relates to novel polyimide oligomers comprising 3,3',4,4′-benzophenone tetracarboxylic dianhydride (BTDA), 2-(3,4-dicarboxy phenyl)-1-phenylacetylene anhydride (PE), and a mixture of 1,3-diaminobenzene and 4,4′-(1,3-phenylenediisopropylidene) bisaniline. The polyimide oligomers demonstrate low melt viscosity (these resins are melt processable) while retaining exceptional thermo-oxidative stability, high glass transition temperature, and good mechanical properties in the cured state.
