Polymer Syntheses

Polymerization techniques

Homopolymerizations
- synthesis of high density polyethylene (HDPE) in gaseous and suspension mode
- synthesis of isotactic polypropylene (iPP) in gaseous, bulk and suspension mode
- catalyst activation and prepolymerization could be performed directly in the polymerization reactor
- hydrogen is continuously supplemented during whole experiment, concentration in gas-phase is kept constant and analyzed by on-line GC
Statistical (random) copolymerizations
- synthesis of linear low-density polyethylene (LLDPE) materials containing higher 1-olefin co-monomers (1-butene, 1-hexene, 1-octene etc.)
- synthesis of statistical copolymers of propylene and ethylene
- synthesis of statistical terpolymers of propylene, ethylene and higher 1-olefins
- hydrogen and co-monomers are continuously supplemented during whole experiment, concentrations of all components in gas-phase are kept constant and analyzed by on-line GC
Sequential multi-step copolymerizations
- 2 step synthesis
  - standard technique for impact resistant copolymer (ICP) production,
  - consists of homopolymerization and copolymerization part
  - before homopolymerization part catalyst activation and prepolymerization could be performed
  - experiments could be performed in gas-gas and bulk-gas modes
  - hydrogen and co-monomer are continuously supplemented during whole experiment and all polymerization steps, concentrations of all components in gas-phase are kept constant and analyzed by on-line GC
- 3 and more steps
  - simulation of up to 5 reactor technologies could be performed according to the customer demands, bulk and gas-phase modes could be combined within one multi step experiment
  - hydrogen and co-monomers are continuously supplemented during whole experiment and all steps, concentration in gas-phase is kept constant and analyzed by on-line GC
Synthesis of special polyolefin materials
- synthesis of polyolefin waxes (PP or RCP) on metallocene catalysts in bulk or suspension mode
- synthesis of amorphous PP on metallocene and single-site catalysts in bulk or suspension mode
- synthesis of highly isotactic, syndiotactic and atactic PPs on metallocene and single-site catalysts in bulk or suspension mode
- synthesis of polybutene or butene-ethylene copolymers in bulk or suspension mode
