POLYOLEFINS: Growth Kinetics Obtained from Single Particle Gas-Phase Ethene Homopolymerization with a Ziegler–Natta Catalyst
Leonhard Mayrhofer and Christian Paulik
A micro-reactor, equipped with a video microscope is used for studying single particle gas-phase ethylene polymerization. Polymerization conditions are close to industrial set points. A standard 4th generation Ziegler–Natta catalyst system has been used. The rate of polymerization is calculated and related to SEM pictures to allow a deeper understanding of the gas-phase polymerization of ethylene. Different Al/Ti ratios and reaction temperatures are examined and explain the behavior of growing polyethylene-particles in a satisfying way.
