Study of EPDM compound mixing process: The effects of molecular architecture

摘要

EPDM is the third largest synthetic rubber and is widely used in applications such as transportation, infrastructure, sports and leisure, and appliance. Ethylene and propylene monomers are randomly polymerized into a chemically saturated, stable polymer backbone, resulting in a polymer with excellent heat, oxidation, ozone and weather aging resistance. A third, non-conjugated diene monomer is copolymerized in a controlled manner to maintain a saturated backbone and provide the reactive un-saturation in a side chain available for chemical crosslinking, as shown in figure 1 (ref. 1).
