ABSTRACT
Several carbohydrates containing polyamides were prepared through polycondensation at low temperature of a solution of 2,3,4,5 - tetra- O-acetylgalactaroyl dichloride with various aromatic and aliphatic diamines. The structures of the acetylated and de-O-acetylated carbohydrate polyamides were confirmed by IR and 13C-NMR spectroscopy. The thermal stability and hardness of the polymers were also investigated. The acetylated polyamides showed higher hardness than the de-O-acetylated ones, which is probably due to stiffness of the polymer chains produced by the acetyl group
