Finally, the shear modulus, GQ, was measured using a pulse shearometer (Rank Bros, Bottisham, Cambridge) as described before (21,22). G was measured as a function of Na SO concentration for 25 w/w latex B with the particles fnlly-coated with PVA. 

Shear Wave Propagation. A pulse shearometer (Rank Bros.) was used to measure the propagation velocity of a shear wave through the weak gels formed by the solutions of HMHEC in dilute NaCl. The polymer concentration range studied was 0.5-2.0%. With this apparatus, the frequency of the shear wave is approximately 1200 rad s" and the strain is <10 . At this strain, n pst systems behave in a linear viscoelastic fashion, and the wave-rigidity modulus, G is...
