Various cured ethylene propylene rubbers having different chemical structures of crosslinking point were prepared using various curing agents and the relationships between the physical properties (tensile strength, elongation, tear resistance, modulus, and hardness) and the chemical structure of crosslinking point were studied.<BR>1) Modulus and hardness depended on the crosslinking density only and did not depend on the chemical structure of crosslinking point 2. Tensile strength, elongation and tear resistance depended not only on the crosslinking density but also on the chemical structure of crosslinking point.
