The present invention belongs to the field of polymer synthesis. In particular, the present invention relates to a method for the synthesis of regioregular polyesters, wherein the polymer ordered structure provides them with advantageous physical-chemical properties, starting from asymmetric diols. More particularly, by the method of the present invention it is possible to obtain regioregular polyesters having high glass transition temperatures Tg and crystalline properties. In the case in which the asymmetric diols are used in a pure enantiomeric form, with respect to the chiral carbon boundto the secondary hydroxyl, through the above-mentioned method it is possible to obtain regioregular and stereoregular polyesters. The method is characterized by thermal and crystalline properties further ameliorative with respect to non-chiral regioregular polymers. 本发明属于聚合物合成领域。特别地，本发明涉及用于从不对称二醇开始合成区域规整聚酯的方法，其中聚合物有序结构为它们提供有利的物理化学特性。更特别地，通过本发明的方法可以获得具有高玻璃化转变温度T和结晶特性的区域规整聚酯。在相对于与仲羟基键合的手性碳，以纯对映体形式使用不对称二醇的情况下，通过上述方法可以获得区域规整且
