    摘要: An aliphatic polyester and/or copolyester, obtained from a polyreaction of at least one monomer from the group comprising lactides, lactones, cyclic carbonates and cyclic anhydrides. To be able to prepare the aliphatic polyester and/or copolyester a reaction mixture is used which contains at least one catalyst of the general formula (M) (X.sub.1, X.sub.2 . . . X), M being a metal selected from the group 3 to 12 of the periodic system (X.sub.1, X.sub.2 . . . X.sub.m) being a substituent selected from one of the families of alkyls, aryls, oxides, carboxylates, halogenides, alkoxides and compounds with elements from group 15 and/or 16 of the periodic system, m being an integer in the range of from 1 to 6, and n being an integer in the range of from 0 to 6, and which also contains a co-catalyst of the general formula (Y) (R.sub.1, R.sub.2 . . . R.sub.q).sub.p, Y being an element selected from the group 15 or 16 of the periodic system. (R.sub.1, R.sub.2 . . . R.sub.q) being a substituent selected from one of the families of the alkyls, aryls, oxides, halogenides, oxyalkyls, aminoalkyls, thiolkyls, phenoxides, aminioaryls, thioaryls, and q and p corresponding to the values for m and n.
