摘　　要：以自行合成的环状膦酸酯(DMDP)为阻燃剂,研究了DMDP阻燃ABS树脂的阻燃性能和热性能。实验结果表明,DMDP的加入可以提高ABS树脂的极限氧指数(LOI);热重分析表明无论是空气还是氮气氛围,DMDP于ABS树脂前分解,有利于促进ABS树脂成炭,提高高温残余量。The thermal stability and flame retardant ABS of a phosphonate ester DMDP which is made by the authors were studied. The results showed that LOI of ABS resin increased after combined with DMDP, and in air or in N2 , TGA showed the fact that the flame retardant DMDP decomposes before ABS resin is the major reason for the accelerated of char forming and improving of char residue of ABS at high temperature.
