Effects of Surfactants on the Linear Rheology of Telechelic Associating Polymers

摘要: The influence of low-molecular-weight surfactants on the linear rheology telechelic associating polymers is studied basis transient network theory. It shown that dynamic shear moduli are well described in terms a Maxwell model characterized by plateau modulus G ∞ and single relaxation time τ. As reported experimentally, peak appears τ (and therefore zero-shear viscosity) with an increase surfactant concentration under conditions junction multiplicity has upper lower bounds formation pairwise junctions allowed. increases, contraction occurs followed extension concatenated chain comprising several connected series. attributed to this extension. On other hand, multiplicity, as suggested Tanaka [Macromolecules (1998) 31: 384].
