Adhesion properties of acrylic pressure sensitive adhesives were examined by means of normal (JKR) contact at room temperature. Cylindrically shaped samples were synthesized in capillary tubes in presence of a cross-linking agent in order to obtain an elastic response. The results reveal power law increase of adhesion at higher rates of interfacial separation. Transition from low- to high-power is revealed and explained as a result of bulk shielding of interfacial fracture mechanism. Further results will be available soon. Bulk viscoelastic dissipation and molecular interactions at the interface are thought to jointly govern this behavior.
