Resumen:
The aim of this work was to analyze the influence of low concentration of different kind of defects, such as pendant or linear free chains, on the viscoelastic properties of polymer networks. Elastic and loss modulus of the networks were found to be a function of type of defect and of both the concentration and molecular weight of either free or pendant chains. Terminal relaxation time of pendant and free chains is in good agreement with reptation theory predictions
