Plastics are used almost everywhere in the world and more environment-friendly plastics are requested from many application areas. Polylactide(PLA) is a biodegradable aliphatic polyester synthesized from renewable resources, such as corn or potato starch. PLA can be prepared by condensation of lactic acid and by the ring-opening polymerization(ROP) of the lactide . ROP is known to produce PLA with high-molecular weights. Many catalysts have been investigated for the polymerization of lactide including complexes of aluminum, zinc, tin. In this study, we constructed late-transition metal catalysts on the surface of nanoporous silica, and examined their performance in L-lactide polymerization . The resulting PLLA were characterized by FT-IR, DSC and GPC.
