An experimental setup and a kinetic study of the polymerization of pro
pylene in liquid monomer with a highly active catalyst are presented.
The purification system for monomer, the catalyst injection system, th
e temperature control system, and the polymerization procedures are de
scribed in detail. Further, reproducibility of the experiments is test
ed, the kinetics are described in the temperature range of 27 to 67 de
grees C, and the influence of prepolymerization in cold liquid propyle
ne is investigated.
