摘 要:A novel polyethylene production process by gas polymerization and slurry polymerization based on metallocene-Z/N catalyst system were reported. The polyethylene thus produced had two melting points with broad relative molecular mass distribution ( MWD ). The relative molecular mass, MWD , melt flow rate determined by the ratio of Ti/Zr and of H 2/C 2H 4. The tensile strength of polyethylene produced by metallocenc-Z/N catalyst was higher than that of LL103A.A novel polyethylene production process by gas polymerization and slurry polymerization based on metallocene-Z/N catalyst system were reported.
