[2E03] Effect of para-substituent in ethylene copolymerizations catalyzed by phenoxy-modified half-titanocene catalysts
In this lecture, we wish to present effect of phenoxy para-substituents in ethylene copolymerization with 2-methyl-1-pentene, 1-decene and with 1-dodecene by phenoxy-modified half-titanocene catalysts. The complexes containing SiMe3, SiEt3 groups exhibited higher catalytic activities than the others in the copolymerizations; efficient synthesis of ethylene copolymers containing hydroxy group has also been attained by using these catalysts.
