Highly active copolymerization of ethylene and dicyclopentadiene with [(eta(1)-t-BuN)SiMe2(eta(1)-C29H36)]TiMe2(THF) complex
A new ansa-fluorenylamidodimethyltitanium complex 1 was synthesized and applied for ethylene-dicyclopentadiene copolymerization using modified methylaluminoxane (MMAO) as a cocatalyst at 50 degrees C. 1-MMAO exhibited the remarkable catalytic activity for the copolymerization and gave a copolymer with high glass-transition temperature of 191 degrees C.
