Conformation and thermal stability of oxidized scleroglucan chains in aqueous NaOH

Summary

The solution behaviour of the polycarboxylic acid derived from scleroglucan (sclerox) has been investigated as a function of NaOH concentration and temperature by means of polarimetry and viscosimetry techniques. In comparison to the native polymer, sclerox is less sensitive to degradation at high NaOH concentration (up to NaOH equal to 0.4 M) and thermally more stable. The viscosity data show a “normal” polyelectrolyte effect and the polymer chains seem to be not stiff. We conclude that at high pH sclerox chains are in a flexible, probably single stranded conformation.
