We showed that the Theological behavior of linear poly(butylacrylate) chains functionalized in the middle by a specific polar core depends on the polar core concentration in the bulk matrices. For low molecular weights of the PnBA and hence high concentration of polar cores, an elastic gel behavior is observed and this is possibly due to a supramolecular network through the matrix. At high molecular weight, this network is diluted and samples are highly viscoelastic liquids. Unlike rheology results, all samples show similar adhesive properties. Even if the supramolecular network allows to increase the level of the plateau, cracks still propagates in the adhesive layer and the failure is cohesive.
