B. Ameduri et al., SYNTHESIS AND PROPERTIES OF AROMATIC TELECHELIC MONODISPERSE DIOLS .1. RADICAL-INITIATED ADDITION OF 10-UNDECEN-1-OL TO NEW AROMATIC ALPHA,OMEGA-DITHIOLS, Macromolecular chemistry and physics, 195(10), 1994, pp. 3425-3443
The synthesis of aromatic telechelic monodisperse diols produced from
the radical-initiated addition reation of a two-fold excess of 10-unde
cen-1-ol and new alpha,omega-dithiols is presented. The dithiols were
prepared by esterification of thioglycolic acid with monodisperse tele
chelic diols obtained by fractionation of oligo(ethylene terephthalate
)s and oligo(tetramethylene terephthalate)s. In all the cases, the lon
g-chain alpha,omega-diols were produced selectively and quantitatively
. The diols are soluble in most organic solvents, contrary to classica
l oligo(ethylene terephthalate)s and oligo(tetramethylene terephthalat
e)s.
