The rheological properties of soft polymer-based adhesives control in a large extent their adhesion properties when viscoelastic losses are dominant (adhesion on high energy surfaces). Peeling properties may be linked directly to linear viscoelastic properties in a large number of cases. The use of molecular models based on the reptation concept and its subsequent improvements (constraints release, dynamic dilution) allow understanding the observed behavior, not only for model linear polymers, but also for complex systems such as blends of block copolymers of various architectures. The use of this approach yields to a predictive understanding of adherence/rheology/formulation relationships. Furthermore, inverting the models allows to "design" molecular architectures and formulations able to fit practical applications for the adhesive industry. © 2008 American Institute of Physics.
