The yielding behaviour of various thermoplastics and thermosets is reviewed in terms of a thermally activated dislocation propagation mechanism. The activation parameters are related to the local polymer structure (entanglement topology, chain flexibility) and to its molecular dynamics reflected in the secondary relaxation processes.
