Temperature dependence of the equilibrium modulus in the cross-linked polyethylene. Static method

Abstract

On the samples of peroxide-cross-linked polyethylene is studied, the structural parameters of crosslinking, the molecular weight between the nodes, the value of gel-fraction, the value and temperature dependence of the equilibrium modulus of high elasticity. It is shown that there is no growth of the equilibrium module with temperature for thick grids of the peroxide-cross-linked polyethylene type. A sharp decrease in the value of the equilibrium module under direct thermal effects on the system with the sample was found.
