The polymeric conditions were optimized to prepare the ammonium polyphosphate (APP) with the average polymerization degree of 390. The effects of preparation conditions such as component proportion, reaction temperature, reaction atmosphere, reaction time, reaction pressure, treating temperature and treating time on the average polymerization degrees of APP were investigated. The following are the optimal technological conditions to prepare APP flame retardant of high polymerization degrees: n[(NH_4)_2HPO_4]∶n(P_2O_5)∶n[CO(NH_2)_2] = 1.0∶1.0∶0.3, reaction atmosphere of wet ammonia, reaction temperature of 270 ℃, reaction time of 30 min, reaction pressure of 2.0 MPa, treating temperature of 250 ℃, treating time of 10 min.
