Abstract
The synthesis of aromatic telechelic monodisperse diols produced from the radical‐initiated addition reaction of a two‐fold excess of 10‐undecen‐1‐ol and new α,ω‐dithiols is presented. The dithiols were prepared by esterification of thioglycolic acid with monodisperse telechelic diols obtained by fractionation of oligo(ethylene terephthalate)s and oligo(tetramethylene terephthalate)s. In all the cases, the long‐chain α,ω‐diols were produced selectively and quantitatively. The diols are soluble in most organic solvents, contrary to classical oligo(ethylene terephthalate)s and oligo(tetramethylene terephthalate)s.
