Abstract:
The present invention relates to the depolymerization of polymers and the recovery of the starting materials used for the production of the polymer. The present invention also relates to the depolymerization of polyethylene terephthalate (PET) and the recovery of terephthalic acid and ethylene glycol.

Claim (Index 20):
A process for depolymerizing of polyethylene terephthalate to terephthalic acid or salt thereof and ethylene glycol comprising admixing polyethylene terephthalate with a mixture of:\n (i) about 3 to about 5% (vol.) of a non-polar solvent capable of swelling the polymer, wherein the non-polar solvent is a halogenated solvent; (ii) about 95 to about 97% (vol.) of a linear C 1 -C 4  alcohol; and (iii) a hydroxide; wherein the admixing is continued for about 1 h; and wherein the process is performed at without applying external heat.
