A new technol. of coupling reaction was studied, by which the simultaneous synthesis of poly (ethylene glycol succinate) oligomers and di-Me carbonate (DMC) was realized by the coupling reaction of ethylene carbonate (EC) and di-Me succinate (DMSu) over various metal Et acetoacetate complexes. Zn (EAA)2 as catalyst had the highest catalytic activity for the coupling reaction. The preferable reaction conditions were as follows: reaction temperature 205-215°C, molar ratio of EC to DMSu 4, molar ratio of catalyst to the total mass of EC and DMSu 0.001, reaction time 1 h. Under such conditions, the yield of DMC was 52.3%, and the intrinsic viscosity [η] of poly (ethylene glycol succinate) oligomer was 0.1174 dL/g.
