Abstract
In an attempt to investigate the flame-retardant effectiveness of aluminum phosphonate on glass fiber-reinforced poly(butylene terephthalate) (GF-PBT), aluminum monomethyl methane phosphonate (MMAlPo) was synthesized. The thermal degradation and flame-retarding performance were studied, and the results were compared with aluminum diethylphosphinate (DEAlPi) which its commercial name is aluminum phosphinate. From TGA, SEM, and FT-IR experiments, it is found that the gas-phase action is dominant for MMAlPo due to the formation of O–P● and P–O· radicals coming from the cleavage of C–P and C–O linkages, while DEAlPi acts mainly in the gas phase along with minor contribution from the condensed phase. The synergism of melamine polyphosphate (MPP) in combination with MMAlPo or DEAlPi was also investigated, and it was found that MPP does not show any synergistic effect with MMAlPo, while a slight synergism is obtainable with DEAlPi. The reason for this finding is discussed related to the differences in thermal degradation mechanism between MMAlPo and DEAlPi.
