Six new polyamides (5a-f) containing p-phenylenediacrylic and hydantoin moieties in the main chain were prepared by direct polycondensation reaction of 4-phenylenediacrylic acid (3) with 6 different h...
New Polyamides Derived from 2,5-Bis[(4-carboxyanilino) carbonyl] Pyridine and Hydantoin Derivatives: Synthesis and Characterization
Polyamides, pyridyl moiety hydantoin derivatives direct polycondensation
2010/4/16
We synthesized 2,5-bis[(4-carboxyanilino) carbonyl] pyridine (4) as a new monomer containing pyridyl moiety by using a 2-step reaction. At first 2,5-pyridine dicarboxylic acid (1) was converted to 2,5...
