摘要：A process for removing contaminants from PET components by mixingethanediol with the PET feedstock at a temperature about the boiling point of
ethanediol and for a time sufficient to convert the polyethylene terephthate componentsto polyethylene terephthate polymers which are soluble in the ethanediol and formbis(hydroxyethyl) terephthalate and produce a product mixture thereof containinginsoluble materials. The soluble polyethylene terephthate polymers, bis(hydroxyethyl)terephthalate and ethanediol are recovered form the product mixture.
