## Abstract Copolymerization of styrene and 1‐butene was first conducted at 50°C with a novel Ti catalyst by using Al(iBu)~3~ (iBu = isobutyl) as cocatalyst. The Ti catalyst is composed of MgCl~2~/TiCl~4~/PhCOOEt/Ph~2~SiCl~2~/SiCl~4~/NdCl~__x__~(OR)~__y__~/Al(iBu)~3~ (assigned as SN‐1 catalyst), wh
## Abstract Two kinds of SiO~2~‐supported Cp^\*^TiCl~3~ (Cp^\*^ = η^5^‐1,2,3,4,5‐pentamethylcyclopentadienyl) catalysts were prepared, using SiO~2~ modified with 3‐aminopropyltrimethoxysilane (NSiO~2~) and the ordinary SiO~2~ as the carrier. The copolymerization of ethylene and 1‐octene was conduc
