Recognition Abilities and Development of Heat-Induced Entangled Networks in Lactone-Derived Glycopolymers Obtained from Ethylene-vinyl Alcohol Copolymers

摘要

Novel glycopolymers have been synthesized from ethylene-vinyl alcohol, EVOH, copolymers activated with 4-nitrophenyl carbonate groups and subsequent coupling reaction with distinct diaminobutylsaccharides. The structure of the resulting glycopolymers has been confirmed by FTIR and ~1H and ~(13)C NMR. In addition, their thermal transitions and degradability have been examined, as well as their rheological behavior in bulk and in water solution. Those glycopolymers that are water-soluble undergo self-association processes and lead to the formation of temperature-induced reversible networks. Furthermore, their affinity to lectins, in particular to Concanavalin A and Ricinus communis Agglutinin, has also been evaluated, showing large and specific interaction.
