The ethylene polymerization and ethylene/methyl acrylate copolymerization with dibenzhydryl-derived Pd α–diimine catalysts will be discussed. These sterically very demanding ligands were prepared in a highly efficient fashion using a new synthetic strategy. The Pd catalysts showed superior properties in olefin polymerization, including high activity (up to 3.2 × 106 g/(mol Pd h)) and high thermal stability, generating polyethylene with high molecular weight (Mn up to 538000) and low branching density (23-29/1000C). Moreover, similar behavior was observed in ethylene/methyl acrylate copolymerization, such as high thermal stability and activity, generating copolymers with high molecular weight and low branching density. In addition, controlled degradation/conversion of waste plastics (including polyethylene, polypropylene, PET, nylon, etc) will be discussed. In this system, various carbon based materials could be efficiently generated. Also, the applications of these carbon materials in super-hydrophobic coating, catalysis and other fields will be discussed.
