The olefin polymerization platform at PTG/e is designed for testing homogeneous as well as heterogeneous catalysts in slurry or solution. An extensive purification system delivers monomers and solvents to four 125 mL and one 1 L autoclaves. Automated catalyst injection and extensive parameter logging (P, T, monomer consumption) make the system ideal for studying (de)activation and propagation characteristics of catalysts. Available solvents are toluene and isopar E. Monomers available are ethylene, propylene and various liquid olefins. Hydrogen and carbon dioxide are available as chain transfer agent and quenching gas, respectively.
