Research progress of organophosphorus flame retardant thermoplastic polyester
The latest progress of organophosphorus flame retardants for polyethylene terephthalate(PET),polybutylene tere-phthalate(PBT)and polycarbonate(PC)flame retardants in recent years were introduced.Organic phosphorus flame retardants have a wide range of varieties,wide applications,excellent flame retardant effects,and also have the effects of plasticizers and lubricants.The types and flame retardant mechanisms of organophosphorus flame retardants were introduced.Emphasis was placed on the flame retardant properties and mechanisms of flame retardants such as phosphonates,phenanthrene phosphates,organophosphinic acids,organophosphinic compounds,phosphoronitrile compounds,and phosphine oxide in thermoplastic polyesters such as PET,PBT,and PC.Finally,the shortcomings and future research trends of organophosphorus flame retardants used in thermoplastic poly-ester were discussed.
