| Abstract: | Poly(L-lactide)(PLLA)was synthesized using staunous octoate as catalyst and L-lactide as monomer.The factors affecting the PLLA molecular weight and properties were studied,including the monomer purity,the catalyst concentration,the polymerization temperature and time.The molecular weight and the degradation properties of PLLA were tested.The results showed that PLLA was a thermal unstable polymer and PLLA had good degradation capability and biocompatibility. |
