FeCl 3 •6H 2 O, RuCl 3 •H 2 O and FeCl 2 •4H 2 O are found to be bulk polymerization catalysts for the ring opening polymerization of -caprolactone, ␦-valerolactone and ␤-butyrolactone. These polymerizations can be significantly enhanced by conducting them in the presence of appropriate amounts of d
