Recoverable and recyclable nickel–cobalt magnetic alloy nanoparticle catalyzed reversible deactivation radical polymerization of methyl methacrylate at 25 °C

Recyclable Ni–Co alloy nanoparticle catalyzed synthesis of well-defined poly(methyl methacrylate) (PMMA, up to 129 500 g mol⁻¹) with low dispersity (Đ = 1.30) via a reversible deactivation radical polymerization technique is reported. The combined advantages of easier catalyst preparation and handling, predictability, simple recovery and reusability up to multiple cycles without a notable decrease in the control over the polymerization make the process an ideal methodology for the synthesis of tailored polymers.
