摘要

A series of polymeric flame retardants(PFRs) containing phosphorus-nitrogen-bromide weresynthesized from spirocyclic pentaerythritol bisphospho-rate disphosphoryl chloride (SPDPC), 2-methoxyl-4,6-dichloro-1,3,5-triazine (MDCT), and tetrabromobisphenolA (TBBPA). The influence of monomer ratio on theirthermal stability was investigated by adjusting theproportion of SPDPC/MDCT (mol/mol) from 80/20 to20/80. The flammability properties of the PFRs blendedwith ABS were evaluated using LOI and UL-94 verticaltest. The structures of the flame retardants were charac-terized by means of Fourier transform infrared spectra (FTIR) and proton nuclear magnetic resonance spectros-copy (~1H-NMR). The results show that the initial temper-ature of decomposition is 274°C and with 35% charringresidue at 500°C when the ratio of SPDPC/MDCT is 50/50. V-0 ratings in the UL-94 vertical test were achieved at20-30% loading of PFRs, when LOI values reached atleast 26.9%. The flame retardancy is strongly dependenton the ratio of P, N, and Br.
