Applications of Coordination Chemistry

Early studies using calcium oxide, carbonate, and carboxylates reported low activities for the polymerization of LA, even in bulk at 120–180 °C. PolyGA and copolymers of GA with CL and L-LA have been prepared using Ca(acac)2, but again high temperatures (150–200 °C) are required. Under these conditions transesterification occurs, although to a lesser extent than in analogous Sn(Oct)2-initiated…
