**Abstract**
 The flame-retardancy and mechanical properties of styrene-ethylene/butylene-styrene block copolymer(SEBS)-based composites, containing SEBS blended with a paraffinic hydrocarbon extender oil, propylene copolymer and magnesium hydroxide(MH) or silane coupling agent surface-treated magnesium hydroxide(m-MH), were investigated. A maleic anhydride-grafted SEBS(MA-SEBS) was used as a polymer modifier for some composites. As the amount of MH or m-MH increased, the flame-retardancy of composites improved, while the TS and EB decreased, and the melt flow property of the composites became poorer. When the oil-filled SEBS(O-SEBS) was partially replaced by MA-SEBS, the TS of the composites increased and EB decreased. Furthermore, replacement of O-SEBS with MA-SEBS and treating MH with silane coupling agent (simultaneously) improved the TS of the composites by a large margin. The phase structure of the composites was characterised using SEM and this revealed that the particle-matrix interfacial bonding was improved through the addition of MA-SEBS. The stability of the composites was investigated by TGA. 21 refs.
