WebFeb 5, 2024 · Critical Overlay concentration and viscoelastic regimes The dimension and interaction of polymer chains in solution depend on the solvent quality and the concentration of polymer in the solution. Changes in solvent conditions and polymer concentration have an observable impact on a solution’s viscoelastic properties ( … WebThe critical overlap concentration of entanglement of polymer coils indicates whether a polymer solution is dilute or semidilute. Here, the reader will find the determination of c * for xanthan gum aqueous solutions in 52 wt.% of dimethyl sulfoxide, often used as non-particulate blood analogues.
