Novel pyridine‐containing hyperbranched polyimides (HBPIs) were synthesized by using a
new triamine 2, 4, 6‐tris [3‐(4‐aminophenoxy) phenyl] pyridine with prolonged chain …

The structure-property relationship of partially aliphatic copolyimides has been studied for
the development of flexible, transparent polyimide films. A structurally rigid cycloaliphatic …

Aromatic—cycloaliphatic copolyimides are synthesized by polycondensation reaction of
dimethylsubstituted diamine-diphenyl methane with a mixture of an aromatic dianhydride …

Some novel semi-alicyclic polyimides based on epiclon and three aromatic diamines are
investigated. The ellipsometry data reveal that the reduced polarizability provided by the …
