Upcycling of Mixed Polyolefins via a Grafting-Dynamic Cross-Linking Strategy
The differences in molecular chain structure, polarity, and crystallinity among mixed polyolefins severely weaken interfacial adhesion in their blends, posing a critical barrier to the efficient upcycling of mixed waste polyolefin plastics. Herein, a solvent-free, one-pot reactive extrusion process is developed, whic...
