## Abstract The indene ligands {1‐C~9~H~7~R} [R = C~2~H~4~(C~4~H~7~O~2~) (1), C~2~H~4~(C~3~H~5~O~2~) (2), CH~2~(C~5~H~9~O) (3)] were prepared by alkylation of indene and used to prepare the SiMe~2~‐bridged indenylcyclopentadiene ligands {Me~2~Si(3‐C~9~H~6~R)(C~5~Me~4~H)}[R = C~2~H~4~(C~4~H~7~O~2~)
The use of crosslinked poly(styrene-co-4-vinylpyridine) having functional groups as the support for zirconocene catalysts in ethylene polymerization was studied. Several factors affecting the activity of the catalysts were examined. Conditions like time, temperature, Al/N (molar ratio), Al/Zr (molar
