Advanced Polymerization (PLA • PGA • PCL)
A four-stage process producing high-molecular-weight, low-polydispersity polymers: pre-polymerization → intermediate polymerization → final polymerization → devolatilization. Supercritical CO₂ improves heat and mass transfer, working together with a static mixing reactor and a specialized vessel for efficient removal of monomers, oligomers, and catalysts.

Process Flow
1) Pre-Polymerization
Formation of oligomers under controlled conditions to limit side reactions and set up high-Mw growth.
2) Intermediate Polymerization
Conversion and viscosity increase under precise conditions.
3) Final Polymerization + Vessel
A static mixing reactor ensures uniform conditions. The stream then enters a vessel where volatiles are extracted with the help of supercritical CO₂.
4) Devolatilization
Dissolved CO₂ acts as an internal stripping agent, ensuring efficient removal of remaining impurities.
