Pracownia Procesów Polimeryzacji

• Badanie mechanizmów oraz kinetyk procesów polimeryzacji ze wzrostem stopniowym oraz łańcuchowym. Obecnie prace w tym zakresie są ukierunkowane na otrzymywanie materiałów biozgodnych i biokompatybilnych (między innymi polimery otrzymywane z takich monomerów cyklicznych jak e-kaprolaktonu i L-laktydu)
• Opracowywanie i implementacja nowych katalizatorów procesów polimeryzacji w tym rozwijanie autorskiej koncepcji łączenia funkcji katalizatora i inicjatora w jednej cząsteczce związku organicznego.
• Badanie materiałów zawierających reaktywne komonomery w łańcuchu głównym.
• Opracowywanie nowatorskich metod syntezy materiałów polimerowych eliminujących konieczność oczyszczania uzyskanych produktów.
