摘要: Abstract The kinetic behaviour of propene polymerisation in heptane using bis(cyclopentadienyl)zirconium dichloride/methylaluminoxane as catalyst system was studied. Propene polymerisations were performed both homogeneous and heterogeneous systems. rate measured by continuously monitoring the monomer consumption. effect process variables such temperature, pressure, Al/Zr ratio concentration on catalytic performance (activity polymer properties) investigated. experimental results systems compared, a model proposed to fit evolution activity at different ratios concentrations for system.
