On the production of ethylene propylene diene monomer

Ethylene propylene diene monomer(EPDM)has wide applications in the auto industry,construction industry,oil additives,plastic runway etc. due to its unique performance. This article summarizes the production technology of EPDM,and its grades,performance and applications. Based on the existing EPDM researches,the development of catalyst for EPDM,core-shell structure spherical EPDM,long chain branched EPDM by situ polymerization,and the copolymer by ethylene and propylene and other dienes are expounded. Meanwhile,the polymerization technology,monomer recovery technology,deactivation washing technology,and flash concentration technology in the solution polymerization of EPDM and the plant production technology of a foreign company in China are studied in detail. It puts forward that the key in the production of EPDM is the polymerization catalyst system. By the upgrading of catalysts,we could produce EPDM with different functions so as to meet the demand of high-performance materials. So,it points out that the development of new catalytic system will become one research focus in the future.
