<p>Elastomer compositions containing ethylene-propylene copolymers or ethylene-propylene-(5-ethylidine-2- norbornadiene) elastomer terpolymers which can be used for the construction of at least two-layer sheets which can be simultaneously vulcanised, in which the lower sheet is SBR rubber. The composition is characterised in that after vulcanising it has high adhesion for layers of SBR, resists ageing, abrasion and has optimum aesthetic properties.</p> |
