摘要： The invention provides ethylene-propylene-diene rubbers capable of imparting excellent heat resistance, weather resistance and dynamic fatigue resistance to vulcanized rubbers made therefrom. The ethylene-propylene-diene rubbers have sulfur uniformly dispersed therein by mixing a solution of the sulfur with a solution of the ethylene-propylene-diene rubber prior to the addition of vulcanization accelerators or other rubber additives to the rubbers. The vulcanized rubbers are particularly suitable for use as automobile components which require dynamic fatigue resistance such as muffler hangers, belts, rubber vibration insulators, engine mounts, tire treads for pneumatic tires, sidewalls for pneumatic tires and white sidewalls.
