This paper discusses the poly(ethylene-co-p-methylstyrene) copolymers prepared by metallocene catalysts, such as Et(Ind) 2 ZrCl 2 and [C 5 Me 4 (SiMe 2 N t Bu)]-TiCl 2 , with constrained ligand geometry. The copolymerization reaction was examined by comonomer reactivity (reactivity ratio and comonom
## Abstract A constrained geometry catalyst (CGC) precursor, Me~2~Si(Flu)(Nβ__t__βBu)ZrX~2~ (X = Cl or NMe~2~), behaved as a single site catalyst with methylaluminoxane (MAO) as cocatalyst, while it developed much diversified catalytic species with AIR~3~/Ph~3~CB(C~6~F~5~)~4~ as cocatalyst. The cat
