Abstract
  Zinc salts of L-proline, D-proline were used in homopolymerization of L, L-lactide and D, L-lactide. Linear PLA oligomer with Mn 2900-3400 Da, can be prepared with zinc (L-prolinate)2 catalyst. Less racemization were occurred in presence of Zn (L-prolinate)2 than Zn (D-prolinate)2. The catalyst structure ...  Read More
