Abstract: Methacrylated phosphate (MAP) and pulverized, UV-cured MAP were used as reactive and additive-type flame retardants in an epoxy acrylate prepolymer, EB600, to compare the difference of their flame retardance. The results from cone calorimetry show that the sample with the cured MAP as an additive-type flame retardant has higher flame retardance than that with MAP as a reactive-type flame retardant. The thermal degradation of UV cured MAP film was investigated with in situ Fourier transform infrared (FTIR). The phosphate unit in MAP degraded completely at 200-270 degreesC. The degraded products further react with aromatic polynuclear hydrocarbons formed above 270 degreesC to yield phosphorus-carbon complexes. To study the contributions of these phosphorus-containing complexes at different degradation stages to the flame retardance, the flammability of EB600 blended with MAP pre-treated at 270 and 400 degreesC, and EB600 blended with MAP without pre-treatment were compared. The results show that the flame retardance of MAP is mainly contributed by the phosphorus-containing degradation products formed at 270 degreesC. (C) 2003 Elsevier Ltd. All rights reserved.
