Nanocomposites of Poly(n-Butyl Acrylate) with Fe₃O₄: Crosslinking with Hindered Urea Bonds, Reprocessing and Related Functional Properties.

ABSTRACT: In this contribution, we reported the synthesis of the nanocomposites of poly(n-butyl acrylate) with Fe₃O₄ nanoparticles (NPs) via dynamic crosslinking of poly(n-butyl acrylate)-grafted Fe₃O₄ NPs with hindered urea bonds (HUBs). Towards this end, the surfaces of Fe₃O₄ NPs were grafted with poly(n-butyl acrylate-ran-2-(3-tert-butyl-3-ethylureido)ethyl acrylate) chains [denoted as Fe₃O₄-g-P(BA-r-TBEA)] via living radical polymerization. Thereafter, 1,2-bis(tert-butyl)ethylenediamine was used as a crosslinker to afford the organic-inorganic networks with variable contents of Fe₃O₄ NPs and crosslinking densities. It was found that the fi
