| 520 | _ | _ | |a Interactions in semidilute solutions of a hydrophobically modified alginate (HM-alginate) in the presence of hydroxypropyl-beta-cyclodextrin (HP-beta-CD) monomer or beta-cyclodextrin polymer (poly(beta-CD)) have been characterized at different temperatures with the aid of rheology and small-angle neutron scattering ( SANS). The viscosity results for the HM-alginate/HP-beta-CD system reveal progressive deactivation of the hydrophobic associations as the concentration of HP-beta-CD increases. For the HM-alginate/poly(beta-CD) system, on the other hand, addition of poly(beta-CD) sets up bridges between adjacent polymer chains and thereby strengthens the associative network. A novel shear-thickening effect is observed at fairly high shear rates for the HM-alginate/ poly(beta-CD) system, and this feature is influenced by temperature. Elevated temperature induces higher chain mobility and the formation of weaker network associations. Analyses of the SANS data disclosed that the association strength in HM-alginate/poly(beta-CD) mixtures increases strongly with increasing cosolute concentration, whereas no effect or a moderate weakening of the strength can be traced in HM-alginate/HP-beta-CD solutions upon addition of HP-beta-CD. The value of the correlation length xi is virtually not affected by the addition of cosolute for the HM-alginate/poly(beta-CD) system, whereas the decoupling of hydrophobic moieties of the polymer upon addition of HP-beta-CD gives rise to a smaller value of xi, suggesting that the size of the heterogeneity patches is reduced. The SANS results suggest that compact association structures are formed in the HM-alginate/poly(beta-CD) solutions. |
