“…When polymer-carrying b-CD moieties interact with aromatic side chains in guest polymers to form inclusion complexes, interpolymer aggregates are formed, resulting in an increase in the solution viscosity. [3,5,[10][11][12] Steadyshear viscosities were measured for 100 g Á L À1 b-CD polymer in the presence of varying concentrations of guest polymers. All the mixtures exhibited a typical behavior of Newtonian liquids (data not shown).…”

Summary: The interaction of a polymer bearing β‐cyclodextrin moieties (β‐CD polymer) with poly(acrylamide)s bearing aromatic side chains was investigated by viscometry to study the effect of collectivity (i.e., interactions at multi‐sites) in macromolecular recognition. The formation of inclusion complexes at multi‐sites caused a large difference in the size of interpolymer aggregates, even though the difference in association constants for complexation of native β‐CD with guest moieties was not very much large.Conceptual illustration for interpolymer aggregates of β‐CD polymer with poly(acrylamide)s bearing naphthyl groups substituted on the (a) 1‐ and (b) 2‐positions (see Scheme 1).magnified imageConceptual illustration for interpolymer aggregates of β‐CD polymer with poly(acrylamide)s bearing naphthyl groups substituted on the (a) 1‐ and (b) 2‐positions (see Scheme 1).

“…There is an obvious enhancement in Figure 4 polymer chains and consequently forms strong overall networks, whereas the further enhancement of HAP-CDE system indicates that the addition of CDE results in strong viscoelasticity enhancements of the HAP-4 solution. The strengthened network structure is attributed to the formation of intermolecular bridges [16,30]. In addition, when the HAP-CDE system is subjected to rapid shear fields, the reinforced networks tend to be disrupted and display shear shinning behavior, which is evidenced by its rheological property.…”

This work evaluates an approach to improve the enhanced heavy oil recovery performance of hydrophobic associating polymer. A polymeric system based on water-soluble hydrophobic associating polymer (WSHAP) and cyclodextrin (CD) polymer was proposed in this work. Addition of CD polymer to WSHAP forms interpolymer bridges by inclusion of CD groups with hydrophobic tails, and thereby the network structure is strengthened. The proposed system offers good viscoelasticity, pronounced shear thinning, and interesting viscosity-temperature relations. Sand pack tests indicated that the proposed system can build high resistance factor during the propagation in porous media, and its moderate adsorption phenomenon was represented by the thickness of the adsorbed layer. The relationship between effective viscosity and oil recovery increment indicated that the proposed system can significantly reduce the residual oil saturation due to the "piston-like" propagation. The overall oil recovery was raised by 5.7 and 24.5% of the original oil in place compared with WSHAP and partially hydrolyzed polyacrylamide (HPAM), respectively.

“…However, for polymers which do not contain highly nucleophilic amino groups, other strategies had to be developed. These include the second frequently applied modification reaction, the formation of amides from monoamino-CDs (18, 22a and b) and poly(carboxylic acid) [26,[42][43][44][45] and its copolymers [46,47]. Guo et al synthesized monoamino-bCD derivatives in which the aminogroups were tethered by alkyl chains of different lengths (13).…”
