Synthesis and properties of aromatic telechelic monodisperse diols, 1. Radical‐initiated addition of 10‐undecen‐1‐ol to new aromatic α,ω‐dithiols

Abstract

The synthesis of aromatic telechelic monodisperse diols produced from the radical-initiated addition reation of a two-fold excess of 10-undecen-1-01 and new qwdithiols is presented. The dithiols were prepared by esterification of thioglycolic acid with monodisperse telechelic diols obtained by fractionation of oligo(ethy1ene terephthalate)s and oligo(tetramethy1ene terephthalate)s. In all the cases, the long-chain a,odiols were produced selectively and quantitatively. The diols are soluble in most organic solvents, contrary to classical oligo(ethy1ene terephtha1ate)s and oligo(tetramethy1ene terephtha1ate)s.
