Synthesis and characterization of piperazine-derived poly(amido-amine)s with different distributions of amido- and amino-groups along the macromolecular chain

Abstract
Four poly(amido-amine)s based on piperazine have been synthesized by poly(acylation-addition) reaction of piperazind with various activated derivatives of acrylic acid. In these polymers, amido-, and amino groups are randomly arranged along the macromolecular chain. These polymers have been fully characterized by hydrolytic analysis, 13C n.m.r., and potentiometric techniques.
