Novel Tailor-Made Ethylene-Phenolic Antioxidant Copolymerization using Ni (II) α-diimine Catalyst: IV. nvironmental Issues Toward Phenol Migration

In this work, the macromolecular polyethylene-based hindered phenol antioxidant is synthesized using Ni-α-diimine catalyst thanks to its higher tolerance toward polar functionalitiescompared to group IV metallocene catalysts and Ziegler-Natta catalysts.It was found that the macromolecular phenolic antioxidant resists against extraction even under aggressive extraction conditions and the oxidation induction time of the sample has not been changed
