The efficient synthesis of poly(ester amide)s (PEAs), which combine polyamide-like mechanical strength with polyester-like biodegradability, has remained a longstanding challenge. Herein, we introduce a unique coordination ring-opening transamidation copolymerization (CROTCP) mediated by a tetranuclear titanium catal...
The chemical incompatibility of mixed plastics poses a fundamental barrier to their circularity. Polypropylene (PP) and polyethylene terephthalate (PET), among the highest-volume manufactured polyolefin and polyester, are particularly difficult to process together due to their divergent structures and stabilities. Here...
The rapid growth of the polymer industry has driven the widespread application of polyester plastics, especially polyethylene terephthalate (PET). However, the nonbiodegradability of waste PET poses persistent threats to ecosystems. Conventional mechanical recycling struggles to achieve closed-loop material circulation...
