Ironbased catalysts efficiency in the ring-opening polymerization of L-lactide is studied.Prepared iron complexes are analysed, characterized and used in the polymerization.The efficiency of the catalysts are determined by analyzing the molar mass, conversion and melting point of the polymers as a function of polymerization time, temperature and used amount of catalyst.
