Because the swelling of polymer gels is a diffusion process of the polymer network, the swelling rate is determined by the diffusion coefficient of a polymer network. The diffusion coefficient (D) includes the polymer–solvent mixing contribution (Dmix) and the elastic contribution from the polymer network (Del). In this study, we experimentally investigateD,Dmix, andDel, using tetra gels whose network structural parameters are systematically controllable. We measuredDand the shear modulus (G) using dynamic light scattering and dynamic viscoelastic measurement, respectively. According to the Tanaka–Fillmore theory, we evaluateDmixandDelusing the linear relationship betweenDandGin the as-prepared state. Consequently, we demonstrate a relation ofD=Dmix+Delin the as-prepared, swelling, and equilibrium swollen states.
