N2 - Slide-ring gel (SR gel) has mobile cross-links that can move freely along a polymer chain. Spatial inhomogeneities are included in a polymer gel network by gelation process. The Scattering intensity, I(q), for solutions and gels are described as follows : (a) Isol(q = 0) ∼ κTφ 2 / KOS, (b) Igel(q = 0) ∼ κTφ2 / (KOS + 4/3μ). Here, φ is the polymer volume fraction, KOS is the elastic modulus, μ is the shear modulus. Since μ is positive, I(q) of a polymer gel is lower than that of a polymer solution. In general, I(q) of a conventional chemical gel is larger than corresponding polymer solution due to spatial inhomogeneities in the gel network. However, I(q) of SR gel decreased with increasing the cross-links density. This means that the spatial inhomogeneities of SR gel decrease by sliding the cross-links and the polymer network behaves like a polymer solution.
