The synthesis of telechelic monodispersed diols produced from the radical telomerization of commercially available nonconjugated dienes (1,5-hexadiene and 1,9-decadiene) with an excess of commercial (2-mercapto-ethanol) or synthesized thio-alcohol, initiated by peroxydes is presented.In each case, the diols were obtained selectively and in excellent yields and were characterized by both 1H and 13C-NMR.The thermostability of these latter diols is much better than that of polydispersed commercially available diols such as polyethylene glycol or poly(THF).Key words:Telechelic diol; monodispersity; radical telomerization; mercapto-alcohol; thermostability.
