Synthesis and properties of low-dielectric hydrophobic polyimides containing alkyl groups and ortho ‑phthalic structures

In this study, two novel aromatic diamine monomers (TBA and DTBA) containing methyl, tert‑butyl and ortho-phthalic twisted structures were designed via molecular design. A series of polyimides were subsequently prepared by one‑step high‑temperature solution polycondensation of th...
