Improving the fracture toughness, flame retardancy and smoke suppression of ABS by core-shell elastic flame retardant particles with P/Si synergistic effect

•Elastic particles ADP@SiR with P/Si and core-shell structures are prepared.•Shell structure improves interaction between matrix and the fillers remarkably.•ADP@SiR achieved good balance in fire-safety and mechanical properties.•ADP@SiR accelerates the pyrolysis of ADP and exerts superior quenching...
