N2 - In a recent series of papers, we have made a study of the shock response of a number of polymers, whilst systematically changing their structure, for example pendent side group size (polyethylene, polypropylene and polystyrene) or degree of halogenation (polyethylene, polyvinylidene difluoride and polytetrafluoroethylene). In this study, we examine a single polymer, polyethylene in two structural forms - high density weight and cross-linked. Results show that overall, the shear strengths of these two variants of polyethylene are similar. However, we note that the rate of change of shear strength with applied shock stress is greater in the cross linked material. We have suggested that this be due to the crosslinking restricting the ability of the polymer chains to move relative to each other.
