N2 - A relation between rheology and structure of high density NIPA gel around criticai point on volume phase transition was studied by a simultaneous rheology and smail-angle neutron scattering measuÆmeiit Just below the critical temperature, the NIPA gel showed softening: G’ and G” get doser (G’> G”). At this temperature, the density fluctuation enhanced along the shear direction corresponding to the shear frequency but not to the shear strength. Itrneàns that this anisotropy is different from that observed in a
statically stretched gel.
