Effect of Polymer-Vesicle Interactions on the Rheological Properties of an Acrylic Terpolymer

Vesicles have been used in different applications including rheology modifiers. The interaction of POSS DCA vesicles with poly(dimethylaminoethyl methacrylate-co- methyl methacrylate-co-butyl methacrylate) and also their effects on the rheology of the terpolymer concentrated solutions were studied. The nonsonicated and especially sonicated POSS DCA vesicles can significantly increase the complex viscosity of the terpolymer solution and can be efficient cross-linkers for it. The vesicular particles may be partially or completely disappeared after exposing to the terpolymer solution as a result of peeling of the vesicular bilayers. The terpolymer interaction with the sonicated vesicles can lead to formation of irregular objects having weak interactions with the terpolymer according to the rheological results
