摘要: Abstract Under atmospheric pressure, nano-polyethylene fibres were prepared via in situ ethylene extrusion polymerization, with MCM-41 and SBA-15 supported zirconocene dichloride (Cp 2 ZrCl ) catalytic systems, respectively. The effects of the geometrical structures surface properties on morphology resultant polyethylene, activity polymerization rate investigated compared various conditions. possible formation mechanism Cp as catalyst was discussed.
