Synthesis and properties of hyperbranched polyimides derived from novel triamine with prolonged chain segments

ABSTRACT 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 segments, ether linkage and meta‐linked units as a BB′2‐like monomer, various commercial aromatic dianhydrides as A2 monomers...
