Unexpected efficiency of cyclic amidine catalysts in depolymerizing poly(ethylene terephthalate)

This article describes studies on the catalytic activity of several nitrogen-based organic catalysts for the depolymerization of poly(ethylene terephthalate) (PET), in which a few cyclic amidines work more effectively than a potent, bifunctional guanidine

Synthesis and properties of long-chain aromatic telechelic monodispersed diols radical-initiated, addition of 2-mercaptoethanol onto α, ω nonconjugated dienes

The synthesis of aromatic telechelic mono dispersed diols produced from the radical-initiated addition reaction of a twofold excess of 2-mercaptoethanol onto original α, ω nonconjugated dienes reaction is presented. These novel α, ω nonconjugated dienes were prepared by addition reaction of m-isopropyl α, α' dimethyl benzylisocyanate with mono dispersed telechelic diols obtained by fractionation of oligo(ethylene terephthalate)s. In these cases, the long chain α, ω diols were produced selectively and quantitatively. The products are soluble in most organic solvents in contrast to classical oligo (ethylene terephthlate)s and posses a lower glass transition and melting temperatures.

SYNTHESIS OF AROMATIC MONODISPERSED TELECHELIC DITHIOLS

The synthesis of aromatic monodispersed telechelic dithiols performed from the esterification of thioglycolic acid with aromatic monodispersed telecholic diols is presented.The diols were prepared from the transesterification of ethylene glycol with the dimethyl terephthalate .In all cases the yields are high and the products are carefully characterized by 1H and 13C-NMR.Key words: Dithiol; telechelic oligomers; ethylene terephthalate derivatives; monodispersity; aromatic compounds.
