“…EPM is well known to have higher oxidative stability and better environmental stability and thermal properties than those of diene‐based elastomers, such as, polybutadiene rubber or polyisoprene (PIP) rubber, due to the absence of unsaturated bonds in their polymer backbones 1, 2. The importance of ethylene–propylene copolymers is increasing strongly based on its superiority in resistance to oxygen, ozone and weathering resistance, chemical inertness, and lightness of color 3, 4. The ethylene–propylene copolymers could be processed with a number of additives and could be the most widely used elastomer for specialty applications, such as, in the automotive industry, rubber mechanical goods and construction materials, and impact modifiers for coatings and engineering plastics 5–8.…”
