Abstract Alkyl hypophosphite flame retardants have attracted the attention of researchers due to their high halogen-free efficiency, low smoke and toxicity, and high thermal stability. At present various alkyl hypophosphites have been successfully synthesized by researchers. The flame retar-dant was added to polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyamide (PA) and other polymers alone or combined with other substances to study its flame retardant properties and mechanism, and has achieved fruitful research results.
Therefore, on the one hand, the structure-activity relationship between alkyl structure of alkyl hypophosphite and flame-retardant mechanism was explained, and the effects of metal ions on flame retardant properties were discussed. By comparison, alkyl hypophosphites with straight and branched chains capture free radicals and form phosphorus-containing small molecular substances during thermal decomposition, which mainly play the role of flame retardance in gas phase. While alkyl hypophosphites with cycloalkyl and aryl groups promote the formation of char layers in the matrix, thus effectively enhance the flame retardant effect in condensed phase. Among them, diethyl hypophosphite has been industrialized and more widely used than cycloalkyl and aryl groups hypophosphites. In addition, by comparing several common metal ions, flame retardant effect of aluminium alkyl hypophosphite is the best. On the other hand, most alkyl hypophosphites have a negative effect on the mechanical pro-perties of polymers, which seriously hampers their application and development. In recent years, a large number of researchers have devoted themselves to the research of high-efficiency alkyl hypophosphite complex system.
In this paper, the research status and flame retardant mechanism of several synergistic flameretardant system are discussed, including metal compounds, nanoparticles and chain extenders. For the alkyl hypophosphite-chain extender system, alkyl hypophosphite releases free radicals to play a flame retardant role in the gas phase. The chain extenders can increase the chain length of polymer molecules and produce cross-linking between chains, which can improve the thermal stability, increase the charring formation ability, and enhance flame retardant effect in the solid-phase. Moreover, the complex system can also improve the mechanical properties of materials and have broad application prospects.
