Abstract:
Novel polyelectrolytes were prepared by conversion of 6-azido-6-deoxycellulose with acetylenedicarboxylic acid dimethyl ester and subsequent saponification. Up to 62% of the azide moieties were converted. The reaction was completed within 48 h using 2 moles of acetylenedicarboxylic acid dimethyl ester per mole of modified anhydroglucose unit. FTIR and NMR spectroscopy were applied to elucidate the molecular structure of the polymers. The polymer degradation was acceptable during this two-step reaction. The resulting biopolymer derivatives were water soluble and reduced the surface tension on water significantly. Moreover, they form ionotropic gels with multivalent metal ions.

Types of Step-Growth Polymers: Polyesters
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the polymer...
