Synthesis of poly(amide-ester)s from 2,6-pyridine dicarboylic acid and ethanoloamine derivatives - investigation of the polymer sorption behaviour towards heavy metal ions

摘要

The synthesis of poly(amide-ester)s from 2,6,-pyridine dicarboxylic acid with ethanolmaine derivatives has been investigated via two different ways. The first one is direct polycondensation with aminoalcohol leadings to a statistical structure. The second one is polycondensation with an intermediate reactive compound, a bis(amide-alcohol), which has only one type of functional group leading to a more regular and defined polymer chain. These new polymers have in the main chain pyridine, ester and amide groups, known to have complexing abilities.
