α-Diimide catalysts have attracted widespread attention due to their unique chain walking characteristics. A series of α-diimide nickel/palladium with different electronic effects and steric hindrances were designed synthesized for olefin polymerization. In this work, we a asymmetric nickel complexes used them ethylene These high polymerization activity, up 6.51×10<sup>6</sup> g·mol<sup>−1</sup>·h<sup>−1</sup>, the prepared polyethylene has moderate melting point molecular weight (up 38.2 × 10<sup>4</sup> g·mol<sup>−1</sup>), branching density distribution between 7 94 branches per 1000 carbons. More importantly, by these exhibits excellent tensile properties, strain stress reaching 800% 30 MPa, respectively.
