Abstract
As the most important polymer by scale, polyolefins like polyethylene (PE) possess various architectures to form versatile products. Branching, polar functional group, cyclic group, or cleavage group are of great importance in these PEs to tune microstructures and thus determine material properties. In this presentation, we show the synthesis of state-of-the-art ethylene-acrylate copolymers via the coordination-insertion copolymerization of ethylene and acrylate under low pressure atmosphere using highly thermostable palladium and nickel catalysts, including linear, slightly branched, highly branched, carbonyl-functionalized ethylene-acrylate copolymers. High to ultrahigh molecular weight copolymers are accessed through coordination-insertion mechanism, which is completely different from those ethylene-acrylate copolymers produced by free-radical mechanism under ultrahigh reaction pressure.
