Abstract: A method for synthesizing regioregular polyesters, starting from asymmetric diols, may provide the polymer ordered structure and advantageous physical-chemical properties. Such methods can make 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, which may have thermal and crystalline properties further ameliorative with respect to non-chiral regioregular polymers.
