Special polyamide chains were polymerized such that they contained reactive sites situated either at the chain ends or at both the chain ends and within the chains. The degree of cross-linking is determined by the amount of a specific silane (cross-link silane), which causes cross-linking by formation of condensed silicon centres. The influence of the degree of cross-linking on the deformation behaviour was studied for uniaxial deformation over a wide range of temperatures and strain rates. A linear dependence of yield stress on the degree of cross-linking was found. The yielding behaviour was treated as an activated rate process and described by a site-change model, in which the height of the energy barrier is determined by the amount of cross-link silane, i.e. by the degree of cross-linking.
