摘要
Previously used poly(ethylene terephthalate) polyester materials and copolymers thereof, and in particular postconsumer polyester materials, are depolymerized and repolymerized to produce bottle grade polymer containing up to 75% of the previously used material. The process involves the solubilization and depolymerization of the previously used polyester material in a transesterification and/or polymerization mixture containing dimethylterephthalate, ethylene glycol and transesterification products thereof.
