| Zusammenfassung: | A process for recovering monomer from multi-component waste material that includes a hydrolyzable polymer, includes contacting the multi-component waste material with water and subjecting the resulting mixture to heat and pressure to form a liquid aqueous portion and a water insoluble portion. The liquid aqueous portion mainly includes depolymerization products of the hydrolyzable polymer, and the water insoluble portion mainly includes components other than the depolymerization products. This mixture is cooled and the liquid aqueous portion and the water insoluble portion are separated. Monomer that formed the hydrolyzable polymer is recovered from the liquid aqueous solution. |
