Viscoelastic behavior of (30-x)GaS_3/2-(50+x)SbS_3/2-20SnS glasses (x=0,5,10) was studied by using parallel plate viscometry. Stress relaxation showed 2 step behavior for all glasses. The main relaxation had activation energies close to the Sb-S bond dissociation energy, which indicates that bond breaking and re-bonding at Sb-S in the glass network as a possible cause of the stress relaxation.
