Abstractepsilon-Caprolactone and L-lactide were ring-opening polymerized by using calcium catalysts treated with propylene oxide and acetonitrile/(propylene oxide). The influences of catalyst concentration and aging temperature, polymerization time and temperature on molecular weight of the polymers were studied. It was shown that this catalyst exhibited a high reactivity and some "quasi-living-polymerization" character and the molecular weight of the polyester could be controlled by adjusting the mass ratio of monomer, to catalyst. Aging treatment of the catalyst and employment of the second organic modifier, acetonitrile, resulted in a higher molecular weight of the polymers. The highest molecular weight obtained was 270 000.
