Polylactide is a biodegradable polymer that is increasingly used in the production of medical devices and environmentally friendly packaging. The search for new catalysts for the synthesis of polylactide that do not contain toxic tin and provide a polymer with a controlled set of properties is an urgent problem. In this study, a catalytic complex based on titanium (IV) is synthesized and characterized. The kinetics of the polymerization of L-lactide in the presence of this catalyst is studied by differential scanning calorimetry (DSC), the reaction enthalpy (–125.1 ± 1.5 J/g) is determined, and the kinetic parameters of the Arrhenius equation are calculated (Ea = 95.7 ± 7.5 kJ/mol, lnAeff = 22.7 ± 1.9).
