Novel Tailor-Made Ethylene-Phenolic Antioxidant Copolymerization using Ni (II) α-diimine Catalyst: V. Utilization as a Master Batch for Polyolefins and Compounding Study

In this work, a novel Ni-catalyzed ethylene-phenolic antioxidant copolymer was synthesized via chin walking strategy to afford highly efficient generation of hyper-branched polyethylene based sterically hindered phenolic antioxidants (HBPE-SHPA) master batch. Thermo-gravimetric analysis of PE/HBPE-SHPA compounds manifests a satisfactory performance of the HBPE-SHPA as a master batch in the thermal stabilization of polyolefins. Moreover, SEM imaging shows a high compatibility between the copolymer and the host polyethylene while clear agglomerates are observed in Irganox 1010 modified polyethylene, in samples prepared at the same conditions
