An evaluation of the activators of static polymer fatigue

In conformity with the kinetic theory 1, 2] a generalized temperature-time dependence of the brittle strength of isotropic polymers is obtained on the basis of a phenomenological model 7]. A quantitative relation between mechanical and thermal degradation is established.Special Design Office for Automation in Petroleum Refining and Petrochemistry, Moscow.
