    摘要: The present invention relates to a process for the production of polyether ester block copolymers wherein the process comprises reacting a mixture of reactants comprising: • one or more aromatic dicarboxylic acid comprising 6-12 carbon atoms; • one or more aliphatic diol comprising 2-10 carbon atoms; and • one or more polyalkylene glycol having a polymeric structure comprising alkylene oxide units having 2-10 carbon atoms; wherein the reaction takes in the presence of a catalyst having a structure according to formula (I); wherein R1 and R2 each individually are a moiety comprising 2-10 carbon atoms. The production of polyether ester block copolymers using such process eliminates the formation of undesired alcohol as a by-product. The polyether ester block copolymers produced using such process show a good balance of mechanical properties. Such process allows for the production of polyether ester block copolymers having a good balance of mechanical properties in a single reaction rather than involving the addition of the reactants to the reactor in several separate feeds.
