Ni 2 P and Ni 12 P 5 containing catalysts were prepared by impregnation of the oxidic precursors on a SBA-15 mesoporous silica or on a CMK-5 nanoporous carbon. Three different kinds of precursors (calcined SBA, not calcined SBA and CMK) were reduced in hydrogen gas stream. X-ray diffraction (XRD) an
## Abstract Ethylene was polymerized using both homogeneous and modified methylaluminoxane (MMAO)‐treated silica supported nickel‐diimine catalysts (1,4‐bis(2,6‐diisopropylphenyl) acenaphthene diimine nickel(II) dibromide) in a slurry semibatch reactor. The effects of catalyst support and polymeriz
