The mechanical behaviour of heterogeneous polymer-polymer blends depends on the mechanical properties of the polymers, on the morphology of the system and on the degree of the mechanical contact between the phases. The three aspects will be explained and illustrated on the basis of results of investigations on the system polystyrene/low density polyethylene (PS/PE) to which graft or blockcopolymers of PS and low density polyethylene (PS-g-PE or PS-b-PE) were added. Although different kinds of mechanical experiments at different speeds and temperature have been carried out, only results of tensile experiments at room temperature will be treated here.
