Millions of tons of polymer waste are generated annually from branched polyethylene-based single-use packaging and agricultural films, constituting a pressing global environmental concern. Nonalternating carbonylative chain walking polymerization offers a promising strategy, whereas fundamentally constrained by the i...

Polyketones are an important class of engineering thermoplastics produced via the carbonylative polymerization of olefins, featuring excellent mechanical strength, chemical resistance, and barrier properties. However, all commercially available polyketones exclusively employ propylene as the comonomer, and the methyl...
Commercial polyolefin plastics are indispensable to modern society; however, their chemical inertness renders them environmentally persistent, thereby contributing to severe plastic pollution and ecological challenges. Accordingly, the development of commercially viable degradable materials with performance comparabl...

Earth-abundant nickel-catalyzed carbonylative polymerization of olefins offers a cost-effective alternative to conventional precious palladium catalysis, but the homogeneous nature of this catalyst causes severe reactor fouling that precludes industrial application. Herein, we report the first heterogeneous nickel-ca...
