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 1):
A process for depolymerizing a polymer comprising an ester functionality to starting materials for use in the production of new polymers, comprising admixing the polymer with a mixture of:\n (i) a non-polar solvent capable of swelling the polymer; and (ii) an agent capable of breaking the ester functionality;\n wherein the admixing is continued for a sufficient time to depolymerize at least a portion of the polymer to the starting materials; and \n wherein the process is performed without applying external heat.
