    Abstract: The invention is directed to a process for preparing a polyester or copolymer containing ester functionalities, and more in particular to a process for preparing a polyester or copolymer containing ester functionalities using metal mediated ring-opening polymerization. The process of the invention comprises providing an optionally substituted lactone having a ring size of from 6 to 40 carbon atoms; and subjecting said lactone to metal mediated ring-opening polymerization using as catalyst a compound according to general formula (I) wherein - M is selected from the group consisting of A1, Cr, Mn and Co; - X and X' are independently a heteroatom; - Y and Y' are independently selected from the group consisting of O, N, S, P, C, Si, and B; - Z is selected from the group consisting of selected from the group consisting of hydrogen, borohydrides, aluminum hydrides, carbyls, silyls, hydroxide, alkoxides, aryloxides, carboxylates, carbonates, carbamates, amidos, thiolates, phosphides, and halides; - L 1 and L 2 are independently an organic ligand linking X and Y together and linking X' and Y' together, respectively; and - L 3 is an optional organic ligand linking Y and Y' together.

    Abstract translation: 本发明涉及一种制备含有酯官能团的聚酯或共聚物的方法,更具体地涉及一种使用金属介导的开环聚合制备含酯官能团的聚酯或共聚物的方法。 本发明的方法包括提供具有6至40个碳原子的环尺寸的任选取代的内酯; 并使用作为催化剂的所述内酯进行金属介导的开环聚合,所述通式(I)的化合物其中-M选自由Al,Cr,Mn和Co组成的组; -X和X'独立地是杂原子; - Y和Y'独立地选自O,N,S,P,C,Si和B; Z选自氢,硼氢化物,氢化铝,碳甲烷,甲硅烷基,氢氧化物,醇盐,芳氧基,羧酸盐,碳酸盐,氨基甲酸盐,酰胺,硫醇盐,磷化物和卤化物组成的组。 -L1和L2分别是连接X和Y的有机配体,分别将X'和Y'连接在一起; 和 - L3是将Y和Y'连接在一起的任选的有机配体。
