Stress relaxation as a method for estimation of the network structure parameters of cross-linked polyethylene
A methodology has been developed to define parameters of the topological structure of the polymer network in cross-linked polyethylene by the stress relaxation method. The obtained experimental data were used to calculate parameters of the polymer network of cross-linked polyethylene. Parameters of the topological structure of peroxide cross-linked polyethylene obtained by stress relaxation and equilibrium swelling methods were compared.
