Abstract: 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 bound to the secondary hydroxyl, through the above-mentioned method it is possible to obtain regioregular and stereoregular polyesters, characterized by thermal and crystalline properties further ameliorative with respect to non-chiral regioregular polymers.
