... formulation of high valent transition metal halide, oxide or oxo-halide with an alkylating co-catalyst such as an alkyl aluminum. Current industrial catalysts include TiCl4/MgCl2/AlEt3 (for LLDPE, Dow), CrO3/Al2O3/AlEt3 (for HDPE, Phillips) and VOCl3/AlEt3 (for EPDM, Shell). These catalysts have low ...
