| 摘要 |
The present invention relates to the separation and recycling of polymer materials containing inorganic additives by means of processing with a solvent under near-critical, critical or supercritical solvent conditions, achieving thereby a segregation of such inorganic additives from the polymeric material. In particular, the yellow colorant cadmium sulfide (CdS) is separated from polyethylene using a water solvent in the critical domain.
