Reprint of: Effect of Mo-modification over Phillips CrOx/SiO2 catalyst for ethylene polymerization

A Mo-modified Phillips CrOx-MoOx/SiO2 catalyst was developed and its ethylene homopolymerization and copolymerization with 1-hexene were systematically studied. The Mo-modification resulted into 67% higher 1-hexene incorporation ability and better short chain branch distribution (SCBD) of the copolymer.
