Abstract
La invención proporciona un procedimiento para la recuperación de polímeros de poliéster, especialmente de polietilentereftalato (PET) a partir de unacorriente de reciclaje de polímeros mixtos, generalmente en forma de envases de bebidas gaseosasno alcohólicas u otros contenedores. Este procedimientoconsiste en: (a) poner en contacto la corriente de reciclaje de polímeros mixtos con un solvente que disuelve el poliéster de manera selectiva, (2)separar el solvente selectivo concontenid o de PET del polímero mixto residual, (3) enfriar el solvente selectivo para precipitar el poliéster, y(4) separar el poliéster así recuperado. En una forma de realización preferida, la corriente de reciclaje de polímeros mixtosse lava quí micamente después dellavado con agua y antes del contacto con el polímero selectivo. Preferiblemente el poliéster recuperado se combina con poliéster virgen y se procesaposteriormente para aumentar su peso molecular.
