Macromolecular Chemistry and Polymeric Materials


Gelation in the system sodium lignosulfonate-hexavalent chromium salt was studied. Isothermal phase diagrams were constructed, and the critical gelation concentrations of the polymer and cross-linking agent were determined. The time evolution of the elastic modulus of the gels was examined.
