Abstract

Poly (lactic acid) has become a hot topic in biomedical field due to good biocompatibility and biodegradability. As an important method for synthesis of poly lactic acid materials, ring-opening polymerization of lactide catalyzed by metal complexes can achieve the controllable polymerization of lactide by selecting appropriate ligand and metal. The metal complex of (LTi-O)2 (L=3, 5-Di-tert-butylsalicylaldehyde-ethylenediamine) has been synthesized and characterized via element analysis and 1H NMR spectroscopy. Furthermore, X-ray single crystal diffraction analysis has been used to determine the molecule structure of the complex (C2/c, Z=4, a=25.495(8), b=16.189(4), c=17.559(5) , =110.209(3) ø, V=6801(3) 3). The catalytic experimental results show that this Schiff-base complex has relatively high catalytic activity and controllability of molecular weights (PDI=1.09-1.24) in catalyzing ring-opening polymerization of D, L-lactide.
