Continuous Depolymerization of Poly(ethylene terephthalate) via Reactive Extrusion.

, 2007
A single-step, extrusion-based process to depolymerize poly(ethylene terephthalate) (PET) has been investigated. The depolymerization is effected by reacting ethylene glycol (EG) with the high molecular weight polymer (glycolysis).
