<p>A method of depolymerizing polyethylene terephthalate and a process for producing a polyester resin. The method comprises heating, melting, and depolymerizing polyethylene terephthalate to be recycled, wherein the heating, melting, and depolymerization of the polyethylene terephthalate to be recycled are conducted at a time using one or more extruders or using an extruder and a reactor disposed at the outlet of the extruder. The polyester resin production process comprises irradiating a reactant with microwaves to accelerate both reactant heating and the esterification of the reactant.</p> |
