Construction of a Furan-Based Core–Shell APP Flame Retardant for High-Performance Polyurethane Composites
Polyurethane (PU) with both high flame retardancy and excellent mechanical performance is highly desired for cutting-edge applications. Herein, a novel furan-based core-shell flame retardant was synthesized through in situ formation of a crosslinked furfuryl alcohol-maleic anhydride-divinylbenzene copolymer (FMD) she...
