Homogeneous Group IVB Catalysts of New Generations for Synthesis of Ethylene-Propylene-Diene Rubbers: A Mini-Review

نویسندگان

چکیده

Ethylene-propylene-diene rubbers (EPDM) are one of the most important polyolefin materials widely commercialized and used in various industries recent years. The production EPDM is based solely on catalytic coordination polymerization processes. development new catalysts processes for synthesis has expanded range products their manufacturing terms energy efficiency, processability, environmental safety. This mini-review mainly analyzes patented data new-generation single-site systems Group IVB complexes including by major manufacturers EPDM. advantages these evident comparison with conventional vanadium introduced into 1960s to date industrial
