This study aims to understand how the specific elastic and dissipative effects developed at large strains by branched and linear species may lead to specific and controlled adhesion properties. The adhesion properties of soft adhesive are governed to a large extend by their rheol. properties. While the linear viscoelastic properties govern the behavior at small strains, the strain hardening effects due to networking and long chain branching, are non linear viscoelastic effects obsd. at large strains, which may improve adhesion properties. The combination of strain hardening and material compliance which drives adhesion properties, may be controlled through polymer structure and macromol. design. [on SciFinder(R)]
