Summary

Thermoelastic data of eis- trans- 1,4- polybutadiene networks swollen in n- octane are presented. On the basis of the theory of the Gaussian chain the analysis of the energy part of the retractive force and of the temperature dependence of the unperturbed dimensions has been carried out as the function of the cis- trans- ratio of the subunits within the macromolecular chains. Temperature invariant macroconformation has been verified by quasi- isoenergetic chains consisting on ∼ 40 % trans and 60 % cis- units within statistically arranged cis- trans- polybutadiene networks.
