摘要： The invention concerns the use of zinc derivatives of general formula (I) wherein: L1 represents a group of formula: -E14(R14)(R'14)(R''14), -E15(R15)(R'15) or -E16(R16); E is an atom of group 15; L2 and L3 independently represent a group of formula: -E14(R14)(R'14)(R''14), -E15(R15)(R'15) or -E16(R16), or together form a chain of formula -L'2-A-L'3-; A represents a saturated or unsaturated chain comprising one, two or three elements of group 14; L'2 and L'3 independently represent a group of formula -E14(R14)(R'14) -E15(R15) or -E16-; E14 is an element of group 14; E15 is an element of group 15; E16 is an element of group 16; R14, R'14, R''14, R15, R'15 and R16 represent various groups, as (co) polymerisation catalysts of cyclic esters.
