Copolymerization of Ethylene/ 2-Ethoxyethyl Acrylate Using Nickel α-Diimine Catalyst

Polyolefins are among the most important plastics due to their versatility, low cost and processability.However, the essentially non-polar nature of polyolefins is the origin of some important limitation of these materials. The introduction of polar functional groups helps to overcome these limitations and greatly improves some other physical and chemical properties. In this study, the ligand 1,4-bis (2,6-diisopropyl phenyl) acenaphthene was synthesized and then added on nickel (II) dibromide salt that produced the 1,4- bis(2,6- diisopropyl phenyl) acenaphthene nickel (II) dibromide catalyst. The structure of the catalyst was fully characterized by CHN and FTIR techniques. Then in order to functionalize polyethylene, copolymerization of ethylene with 2-ethoxyethyl acrylate (EEA) using this nickel α-diimine catalyst has been investigated. Structures of samples were characterized by TGA, DSC and 1HNMR techniques
