By polymerizing a non-conjugated diene along with ethylene and propylene, these elastomer products could be cured with traditional sulfur curing systems that had been established for natural rubber and synthetic rubbers such as SBR and BR. In the nineteen sixties DSM completed its proprietary Keltan
