Department of Polymerization Engineering

In the department of polymerization engineering the main activities has been focused on slurry, bulk and gas phase polymerization of olefins. Also polymerization processes of styrene such as RAFT and ATRP polymerizations are among the areas of interest.
Research Fields:
  • Kinetic study of polymerization processes of olefins
  • Modeling and simulation of olefin polymerization
  • Study of structure -properties relationship of polyolefin's
  • Synthesis and characterization of Z-N catalyst supports
  • Homo & co polymerization of styrenic polymers
  • Preparation of Polyolefin/clay nanocomposites via in situ polymerization

Polymerization Engineering Laboratory:
In addition to general facilities, the laboratory is equipped with 4 automatic high pressure polymerization set-ups comprising of Buchi reactors which are connected to feed purification units. The systems are capable of monitoring and saving polymerization conditions during polymerization. The systems are directed towards:

  • Slurry phase set-up for ethylene polymerization
  • Gas phase set-up for ethylene/propylene polymerization
  • Bulk phase set-up for propylene polymerization

Other Facilities:
The group has developed a setup for preparing MgCl2 supports with predefined PSD.
