Poly(Lactic Acid) (PLA) for biomedical application – synthesis of biocompatible Mg catalyst and optimalization of its use in polymerization of lactide with aid of DOE

Agnieszka Gadomska-Gajadhur , Ludwik Synoradzki , Paweł Ruśkowski


Efficient, original synthesis of magnesium 2-ethylohexanoate via reaction of metallic magnesium with 2-etylohexanoic acid was achieved. The activity of MgOct2 as biocompatible catalyst of lactide ring opening polymerization was examined. The process was successfully optimized by using factorial and rotatable designs. PLA of Mw =34 000 g/mol with high lactide conversion (>95%) has been obtained. Due to the use of biocompatible catalyst (lack of tin),it can be used in medical and pharmaceutical application.
