Abstract The phosphorus element hybrid polymer (OPP) was synthesized by step-reaction polymerization using phenyl dichlorophosphate (PDCP), ethylene glycol (EG), methanol, and the aluminum hydroxide-phosphorus hybrid polymer/polystyrene flame retardant composite (ATH-OPP/PS) were prepared by mixing nano-aluminum hydroxide (ATH) and OPP into polystyrene (PS). The structural characteristics and average molecular weight of OPP were explored by FT-IR and gel permeation chromatography (GPC). The thermal stability and flame-retardant properties of the composites were evaluated by TGA, limit oxygen index (LOI), microscale combustion calorimeter, SEM and XPS. The thermal decomposition activation energy (E_a) of composites were calculated by Flynn-Wall-Ozawa (FWO) method. The results show that thermal stability and LOI were improved and peak heat release rate (PHRR) and total heat release (THR) reduced due to ATH/OPP as retarded system. E_a increased with the increase of degradation conversion rate.
