Abstract
Abstract Efficient incorporation of 2-methyl-1-pentene (2M1P) has been observed in copolymerization of ethylene with 2-methyl-1 -pentene (2M1P) using Cp*TiCl 2 (O-2,6- i Pr 2 C 6 H 3 ) ( 1 ) - MAO catalyst, and the resultant polymers were poly(ethylene- co -2 M 1 P)s that possessed high molecular weights with unimodal molecular weight distributions as well as with uniform 2M1P incorporation. The tert -BuCp analogue, ( t BuC 5 H 4 )TiCl 2 (O-2,6- i Pr 2 C 6 H 3 ) ( 2 ), showed less efficient 2M1P incorporation than 1, whereas 2 showed better 1-hexene incorporation in ethylene/1-hexene copolymerization. The steric bulk in both 2M1P and the cyclopentadienyl fragment thus affected the comonomer incorporation in this copolymerization.
